Yep. That looks like you got yourself a scrappy double wedding ring quilt. Are there any four square pieces to go with the arcs or any melons? If you would like to finish the quilt I suggest you look for some Double Wedding Ring quilt books, choose one that you like and make a small one before you attempt to finish someone else's work. I have a DWR that I finished last year and am in the process of hand quilting it. I have renamed it the "quilt from hell" only because I started it about 20 years ago and it was hard to get it all the fit together nicely. But I will be gifting it to my grandson and his wife and there are no Quilt Police in their home.
