Forgive me if I don't explain this right, the center was template cut and sewn together, no paper piecing. The circle in the white square was turned under with interfacing then pressed the inner circle to it. The pattern called for me to sew the two together, I couldn't do that, it was just to difficult to ease the small circle in. I bit off a bit more than I can chew here, but I have learned alot and am enjoying the challenge. Is it selvagable?
