I was wondering about the "spy quilt", also. I don't remember seeing that pattern in any of my quilt magazins.
Scrap quilts are all that I make, but I'd like ideas for using up small pieces of fabric. Because of my disability, the sides of each individual piece must be straight so that they can be cut with a rotary cutter. I tried to cut around the curve on "drunkards path" block with a small rotary cutter but found it too difficult, impossible not difficult, due to my shaking hand. My favorite quilt block is the 9 patch, but I also make 4 patch, brick wall, tumblers, and even string quilts. I can't bear to throw away any scrap large enough to sew onto another piece of fabric.
