Here is my first experiment with a pojagi inspired piece. It will be a window cover on a long narrow window by a stairwell in my son's apartment. I am delighted in the way it looks like stained glass. The technique is simply joining pieces with flat-felled seams (like the inside seam on your Levi's). Pojagi, also called bojagi, originates as a Korean art used for wrapping cloths. I found a great tutorial here at The Silly BooDilly blog. The flat-felled seams are her tutorial #2 on the post.
