I have not started, but have two different centers in mind. I may do two, or I may just do one, depending upon needs of the RR, and how these centers come out. I'm working on one, and am waiting to get a paper piecing tutorial so I can decide about the other. I'm a nervous wreck...I've been trying to teach myself paper piecing but really need it demonstrated. I can't visualize what the books are doing...Yikes...
