I think you should finish the quilt. I have one that I started approx 35 years ago. Have all the material that I am going to use plus have most of the flowers made. Am planning on using the white diamond pieces to join the flowers. Started like I said approx 35 years ago but my fingers got so sore that I put it in a bag and it sat in a spare closet for a few years. When we moved 23 yeas ago, I came across the bag and put it in a container. Told myself that I was going to work on it again but with moving, never got going on it again until recently. I joined a quilting guild and bring it with to our Stitch and Sew meetings once a month. It is more fun working on it while visiting. So don't give up on it. Your flowers look beautiful. It would be a shame not to finish it. Hope to see a picture of it completed.
