Do you have odd socks with no mate?
Use them to make a sock cozy.
Simply cut the sock and slip on a glass or cup.
Turn down the edges of the sock or roll them down to hide the cut edges.
Great idea if you have people over, they can have a personalized cup to know which is theirs.
This is also a very easy project for the kids to make.
The sock cozy could be embellished with beads, buttons, or other decorations.
