Debbie, it looks like someone tried to guess how to make a Dresden Plate pattern, that was all the scraps they had. I own about 1,000 quilt books with all kinds of patterns.
The more I looked at it, that was my guess, try fitting the triangles between the others on another block, or use it as the center of the quilt and keep adding triangles all the way around, and when it's big enough add you border, I go to a lot of yard sales and estate sales looking for books and fabric, and picked up some quilt pieces the other day at an estate sale, some one started and I had never seen the pattern before. I'm going to another one Saturday, I hope this info helps.
Ms Mac :-)
