Sock monsters are one of my favorite on-the-fly entertainment tricks and a cost-free way to creatively reinvent solo socks. If the simple Sharpie-drawn monster is beneath your crafty standards, try Monster Munch's free downloadable pattern and instructions. It's a quick eight-step process that involves two socks, two buttons, a bit of felt, and some stuffing. Try it once and then teach your grade schooler to make their own.
