vintage cotton print patchwork quilt block pieces, hand stitched triangles double-sided

Huge lot of vintage hand sewn triangles for a quilt, or maybe pot holders? There's about 150 double sided triangles here, all about 11 1/2" on the long side, 6" and 6" on the sides of the point. They'd make squares about 11 1/2" x 12" overall.

Lots of 50s and 60s cotton fabrics and some great prints, but these were all made from 'used' fabrics, and some pieces do have spots and/or yellowing.
