This unfinished parlor throw or quilt was made in Pittsburg, Pennsylvania, by Mary Dickson Watson (born about 1840). The raised or “biscuit” patchwork was done by basting 3 ½” silk squares to 2 ½” cotton squares with a pleat at the center of each side. Cotton batting was put under the center of each square. The covered squares were then machine-stitched together to make this colorful top.
