Vintage embroidered patches, I love School. These are supposed to be stickers, but they are losing stickiness, they don't stay stuck to the paper backing.
You could sew these on to backpacks etc, or just use a new fabric glue. Or maybe use an all-purpose glue to attach them to pinbacks.
There's 50+ 2 1/4" x 2 1/4" patches here. Paper backing is yellowed and worn, patches themselves look fine. Nice and bright and clean.
