Wanted to pop in and show you a little quilt I'm doing for an auction held by NQA. It measures 18" square and I just need to stitch on the binding. The puzzle technique was taught in a class given by our charity guild -- Coastal Quilters. We all did one and we were told to bring a coloring book drawing (I used a drawing from EQ -- I'm not sure if it came with EQ or was an add-on program--I'm thinking the latter). Once in class, we traced the drawing onto freezer paper, then just drew random lines around the drawing, cut out all the freezer paper pieces on the drawn lines, and fused our chosen fabric, etc. I'm sure I'm not explaining it correctly, but it was easy and fun. I did mine in a quilt-as-you-go method, using satin stitching to hide the fused section joins.
Everyone's is different, depending on the drawing they used and their individual fabric choices. Didn't it turn out cute, though?
