Looks like a quilt would fit in there...

We're having hardwood floors put in our living room and dining room, after 25 years of wall-to-wall carpet.  Not only are the floors gorgeous, but I realized that the six-foot-long boxes that the wood planks came in are just the right shape to ship a rolled-up quilt.

I saved out several of them for future use.  Many of my quilts need a box even longer than six feet, but I'll be able to put two of these together for extra length. 

When I had to ship my Quilt National piece to Ohio (twice) I had to pay UPS $20 to build a 90-inch box, by taping together two smaller cartons.  And they made a mess of it, so that the wonderful volunteers at QN had to virtually rebuild the box to send the quilt home after photography.  I know I'll be able to do a better job than the klutz at UPS.  Now all I need is for one of the big quilts to get into a show.
