One of the loudest, most insistent images you can add to your art work is a pointing finger. Who can resist looking where the finger points?
My finger-pointing image repertoire got a big boost in the fall when the movie "Salinger" came out, its ads featuring a hand-drawn illustration of the famous author with a finger to his lips. The ad ran frequently, in different sizes, sometimes in color, sometimes in black-and-white. Salinger's finger showed up several times in the collages.
I make abstract art -- usually with a needle but sometimes with a pen, brush or camera, scissors and glue, pliers and wirecutters, whatever is there. I have a husband, two sons, seven sewing machines, a big messy studio and lots of other people's art. Life is good!
