Here's a few things I have been up to. We have a group that makes a center and we add to it. If you scroll down you will see some of there quilt tops. But these are 2 I really liked doing the one I made a template for the half circle I added to hers and then I appliqued it with a scalloped stitch.
The other is my daughters center she embroidered on my machine and then I added the outer edge.
