its a pattern by Quilters Haven call "circles". it has a circle template that comes with it. you cut 8" squares, three layers, 1. batting, 2, top fabric right up and then 3. backing face down. draw your circle and then stitch all the way around. Slit close to one edge (will be under melon that is turn under). then you sew them together to form the melons...really fun to do and glad IJM likes it
I'll try and find a web site...be back
