Why rip it when you can cut it. If you don't like the borders, cut them off. If you want to salvage the blocks cut them apart.Personally I think you could do some lovely quilting down those wide columns of solid fabric. If you are going to toss it anyway, cut out what you want and make pot holders out of the remaining. I do like the suggestion of donating it. You mya not like it but some homeless person would love it's warmth. Quilt it up and donate it to a shelter. I do like your stars! Nice work piecing all of it. Good luck!
