Quiltmaking 101 -- freehand and curved seams 2


If you have chosen to cut your quilt pieces freehand instead of using a ruler, or if you are deliberately using curved seams, you face a construction issue: how to make the finished seams lie perfectly flat.  If the curves are gentle -- think the profile of a watermelon -- and if they curve in the same direction, you can usually just sew one to the other and they will be fine.

This approach works as a new construction method if you layer two pieces of fabric on top of one another, then cut a gentle curve through both layers.  Swap the pieces and stitch them together.























The piece above was made with three cuts, not one, and of course it yielded a mirror image piece with the same curves but the opposite color arrangement.  Note that the middle seam ended up wonky, with the black quite a bit longer than the orange, even though they were presumably the same length to start with.  This is not a failure of sewing skill; it's an unavoidable and unpredictable result of the process of sewing two bias edges together.

When this happens to you, and it will, don't feel guilty, don't try to rip the seam and redo it, just trim off the edge.

The just-sew-it approach also works with random pieces that you may find in your stash and want to sew together.  As long as the curves have approximately the same radius, and point in the same direction, you'll probably be fine.  But if they point in opposite directions, or are too radically different in profile, you'll end up with bulges or clots.  Plan ahead, and don't do that.

These pieces will most likely go together beautifully.  


These pieces won't.

With gentle curves the actual sewing will be very much like holding straight edges together -- no big deal.  But when you sew more pronounced curves -- as the watermelon profile becomes more like a cantaloupe or a grapefruit -- it's harder to maintain the proper seam allowance because the two edges are so different in profile: one a distinct hill and the other a valley.  It will be easier if you hold the "valley" curve on top and the "hill" on the bottom, even though that makes a lousy mnemonic.

Establish the seam allowance at one end of the seam and put your needle down through both layers.  If possible, set your machine so it automatically stops with the needle down, to make sure the pieces don't slip out of alignment when you stop to reposition the fabrics.  Carefully align the edges of the two layers and stitch for maybe a half inch.  Stop needle down, and reposition the fabric.

Make sure you can see the edge of the under layer, because it curves away from the needle and if you're not careful you can sew right off its edge.  If you stitch with a hint of pink peeking out from under the yellow, you'll be fine.  Yes, this is slow going, but this is how you get a perfect seam.

The top layer will form ruffles behind the needle as you stitch around the curve.  Don't pull tight on the top layer as you hold it in position; if anything, ease just a bit of extra fabric into the curve as you sew.

After you get to the end of the seam, flip it over and check whether you have inadvertently sewed any pleats into the bottom layer of fabric that you couldn't see.  If you have, get your seam ripper and open the seam for a quarter inch on each side of the pleat.  This time sew with the "hill" side up so you can watch carefully as you ease the fabric under the needle and get it smooth this time.  It's important to fix any glitches before you press, while the fabric is at its most flexible.

Sometimes you'll sew curved edges together, press the seam, and it looks as though everything is perfect.  But when you flip back to the right side, you'll notice that the two edges didn't match perfectly. When you turn that curved seam over, run your fingernail along it from the downhill side to find any hidden pleats.

If you find one, don't worry -- it's very easily fixed.  Turn it back to the wrong side and notice that the iron has creased the fabric at exactly the right place to give you your perfect seamline.  Restitch the seam along the crease mark and the curve will look exactly as it did before, except the new stitching will have closed the pleat.

Looks great from the front, but....


....there's a huge gap at the end of the seam between black and  yellow.


Go back and stitch exactly on the crease line. 

You will note that all the curves in this post go in one direction only -- no S-curves or multiple-winding roads.  If you want to sew these more complex curves, you'll need a more precise method to make them lie perfectly flat; stay tuned for the next tutorial.

And then there will be more about pressing curved seams in a further installment of Quiltmaking 101.  Wait and read that before you take your seam to the ironing board.

Quiltmaking 101 -- freehand and curved seams 1


The rotary cutter is a blessing for anybody wanting to make straight edges, a huge improvement over tracing around a template with a pencil and then cutting along the line with a scissors.  Rotary cutters, paired with rulers, make perfectly straight edges with very little work.

Although traditional quiltmakers have always worked with ruler-straight edges and seams in most block construction and when sewing blocks together, contemporary artists often prefer the looser look of freehand cutting.  You still use the rotary cutter and mat, but instead of lining your blade up against a ruler you cut without a guide.  Even when an edge/seam looks almost straight, you can see the artist's hand in a freehand line where you don't get that vibe from a ruler-cut line.

On the left, freehand straight lines; on the right, ruler-cut:

Can you see the difference?  It's subtle, especially if you're only looking at one block, but gives a different character to the finished quilt.

The problem with freehand cutting is friction.  In an ideal world, your fabric wouldn't be the least bit slippery and your rotary cutter would be so sharp and roll so smoothly that it would cut a clean edge without pulling at all on the fabric.  You would finish your cut with the two pieces of fabric exactly in their original places, so perfectly aligned that you would barely be able to see that they were cut at all.  In the real world, the blade catches just a bit and pushes or drags the fabric along with it a hair as it rolls along; you'll often see a bubble of fabric moving ahead of the blade as it cuts.  This is especially true if you are cutting two layers of fabric at the same time.

To prevent this, and to make sure that the cut goes exactly where you want it to, it's helpful to hold the fabric in place as you cut.  For short cuts, you just hold it down with your fingers (being careful, of course, not to cut yourself).  For longer cuts, anything over a foot, I like to hold the fabric in place with the plastic ruler, but keep the cutting line at least a quarter-inch away from the edge of the ruler.  That way you get the best of both worlds: the freedom of the freehand cut, where you can wobble or curve your line if you want, plus the ease of cutting fabric that stays where it's supposed to.

When you're joining almost-straight strips and blocks, you can pretty much just put them together and sew a straight seam; the fabric will have enough give to press flat. But as the seams get longer, or as you're joining long rows of blocks, or if your freehand cut had a bit of curve to it, you have to be a little more careful.  If you're not, you can end up with a hill or a valley or both, and even the most diligent pressing won't make them disappear.

Stay tuned for tips on how to sew not-straight pieces of fabric together and still have them come out perfectly flat.

Quiltmaking 101 -- batting cleanup


Several years ago I started a series of blog posts that I call Quiltmaking 101 -- tutorials on all the basics of machine-pieced quilts.  Early installments deal with how to use the rotary cutter, how to stitch seams and how to press.  Moving along through the production process, you can learn how to efficiently sew block-to-block quilts together, how to put the quilt sandwich together, and how to quilt it.  Finally, you can learn how to finish the quilt, with bindings or facings, and how to put a sleeve on for hanging.

I think that somebody who never saw a quilt before could probably learn 99 percent of what she needed to make one by following this series of tutorials.  If you want to read them, they're all right here.

But I realized recently, as I went back to check out one of the posts, that I had left some gaps in the instruction.  Most embarrassing, I realize that I never explicitly discussed freehand cutting -- the heart of improvisational quilting -- and how to sew together a quilt with curvy pieces.  So I am putting together a series of posts on piecing curves.  By that I mean both gently curved seams like these:

and more severe curves like these:























I'll be posting these new tutorials in the next couple of weeks.  Meanwhile, I invite you to look at the Quiltmaking 101 link above and tell me if there are other basic skills that you'd like to see additional tutorials on.

Kimono everywhere 4 -- my pieces


For our Kimono Challenge I made two small pieces using only small scraps.  I searched out torn and frayed bits and areas where the kimono had been mended in the past.  As we went through all the garments we had noticed that many of them had been mended, generally by cutting a piece of matching fabric larger than the hole, placing it underneath and invisibly stitching the layers together.  I found only one piece with a large mend, and turned it upside down so the patch was obvious.























I sewed everything down to a background mostly using running stitches, but late in the project started adding french knots.  When I was using silk or rayon thread the knots were tedious and small, but then I found a spool of 28-weight cotton Aurifil thread in a variegated ivory-pink-coral-maroon colorway, which made beautiful fat knots and was very easy to work with.  So I made large masses of knots, piling them right next to one another or even climbing on top of each other.  I love this effect, and it's a seductive technique for those of us who enjoy going into a zen state and stitching for hours at a time.

The other two pieces didn't have mends to showcase but I used the same techniques -- raw edges on the bits of silk used in the collage, lots of running stitches to hold them down to the background layer, french knots, dangling threads at the bottom.

These pieces eventually need to be mounted in frames or on panels, but not right now.

A quiltmaker's dilemma...


Last summer I took four quilts out to hang at a doctors' office as part of a program that PYRO Gallery has had for a few years.  Twice a year we hang a new "show" of as many as 50 pieces of art at the office, and in return the doctors agree that a certain amount of art will be purchased.

The good news is that one of my quilts has indeed been purchased, and though I will be sorry to see it go I know it will be going to a good home.  The quilt is "Linear B," which was the ultimate fine line quilt -- it consisted entirely of machine-pieced fine lines!

Each of these little strips is cut from commercial striped fabric and is approximately one-eighth inch wide.

Linear B won the juror's choice (aka second place) at Art Quilt Elements in 2016 at the Wayne Art Center in Wayne PA.

When we went to hang the art at the doctors' office that quilt was the only tall, skinny piece that anybody had brought, so it got to hang right by the elevators in the main lobby.

So this week I went out to collect the quilt and pack it up to be shipped to its new owner, and was appalled to see that in the months since I left it, it had warped!!

Instead of lying flat against the wall, as in that installation photo above, it was gaping at the sides, as much as four inches away from the wall in the center.  As you walked off the elevator, you got a great view of the back of the quilt.  Yuk.























Obviously I have to do some remedial sewing before this quilt can be delivered, but what?  Do I want to sew three additional horizontal sleeves with slats at the quilt's shoulders, waist and knees?  Or should I sew vertical sleeves along the edges of the quilt and slip a very tall rod into each one to hold the sides against the wall?

If any of you have had experience with this kind of gapping, please let me know what you did and whether you're happy with the solution.  The new owners are waiting!!

Thanks in advance...

And by the way, I put up "Big Ice" next to the elevators after I took down "Linear B."  Maybe it will go to a new home too.

Kimono everywhere 3


I realized in looking back on past posts that I never finished telling you about the Kimono Challenge that our local fiber and textile arts group held last year.  (Look here and here for the first parts of the story.)  It comes to mind now because we have just learned that later this year we are going to have a public exhibit of all the art made in the challenge.

Several people made wall art from the kimono in our challenge project.






















Particularly intriguing in this one is the "Japanese" lettering in the center right of the piece.  It was achieved by cutting up some silk-screened fabric in an allover pattern and sewing it in vertical strips!













































This one combined silk with handmade paper and Japanese paper, with hand and machine stitching.

I'll show you what I made in the next post.
