Lay socks flat, one on top of the other. Beginning at the toe end, roll up the socks, keeping the "non-heel" edge even as you roll. Place a rubber band on the lower half of the sock roll to secure it. One edge of the sock roll will be flat
Another teacher gift idea. Pampering in a jar. Use a mason jar, put some nice warm fuzzy socks, lip balm, a small thing of hand lotion or bubble bath, and some chocolates. A little bit of ribbon and a tag after you put them into the jar.
