Fabric Quilt Pieces Lot of 100 Patchwork Sewn Half Stars Vintage? Cloth

This is a lot of a total of 100 patchwork quilting pieces; 93 are 1/2 stars and the other 7 are straight rows. Each 1/2 star has 6 pieces machine sewn together. I think that they are cotton and the fabric seems older but not antique. Maybe from the 1970s? Everything is VERY CLEAN and ready to use! They measure about 12 3/4" from side to side and about 7" at the tallest point. Size: 12 3/4" x 7"
