After my fabric was painted and heat set I put my sky fabric , right side up, on top and pinned the two pieces together. These two pieces of fabric will be flipped over and then I will stitch around the outside edge of the sky fabric. I had to re-paint my sky fabric because I didn't like the light areas that was on the other piece of sky fabric I painted. When I painted the first piece of sky fabric I didn't have a firm ,smooth surface to paint on and some of the areas were uneven. I am much happier with the new piece of fabric and I think it will work much better for this quilt.
