...28 to go. Excuse the wrinkles - they're not fully pressed.
These took about 2 1/2 hours. I'm still trying to figure out the most efficient assembly process. My mom suggested you take all of one color rings, say the green ones, and assemble all 15 of them. Then add the centers between them and the arcs on the outside edges. That will be the next scenario to try. The one on the left was assembled by adding the arcs around the melon wedge shapes and then sewing those pieces to the center. The one on the right by adding the green arcs to the melon wedges, then those to the center, and after than adding the pink arcs and squares. I'm thinking Mom had the right idea. So I'll assemble two more green rings for the top row and add the center, and see how that goes.
Notice the four-patch in the top center. I cut a curve in the top square so I would have a smoother curve to bind. All the wedding ring quilts I've seen had either a tight inner or outer corner. No thanks.
