I just finished this fan quilt and noticed that it looks a lot like a selvage quilt. First I cut a ton of one-inch strips from my 1940-1970's era stash. Then (without using a foundation) I sewed the strips together starting with a 1/4 inch seam allowance, then gradually increasing to a 1/2 inch seam allowance. Doing this with each added strip produces the fan effect. After piecing, press flat then using a square template, trim. The border is made of small fans. I love this busy quilt.
