I usually work on one for at LEAST a month! I typically piece rather complicated patterns since I love little details. I spend a few days choosing colors, a few days cutting fabric and then begin to piece. I have to take frequent breaks because I get bored doing the same thing over....and over......and over. I don't have any UFO's but I do take my time piecing a quilt. Sometimes if I get tired of looking at the same fabrics, I'll start a second quilt and then it will take me twice as long to finish!
