My initial response was "one and done", but then I realized that I've made several Lone Stars for baby quilts and several Attic Windows I Spy for toddlers. Currently on a "row" quilt binge. Made rows of bunnies/flowers/eggs for Easter and am currently working on rows of trees/mountains/houses made from batiks.
I can guarantee that the minute I see "squirrel" on Pinterest, I'll start with something totally new.
