At Christmas, I did something similar. I copied a pattern I saw in a sewing machine ad in one of my quilting magazines. No pattern, just went off the photo. I was a few inches short on one of the fabrics, which also was a batik. I went thru the waste basket and sewed together all the little cut offs and scraps, some of them were less than an inch wide, and had just enough to complete the quilt. The fabric was so busy that the extra seams were not noticeable. Any scraps you can use??
