Snake 'Sock Puppet'
One day I stuck a little red sock on my two-year-old's hand and told him it was a snake. He had a great time making hissing sounds and sliding his little 'snake' across walls, windowsills, and tables. He also refused to give the sock back. After a few days, I decided to make him a little snake, in the style of a sock puppet (obviously with some extra cool touches) since he liked it so well. I'm pleased with the result, and he was, too - although he still refused to give back the red sock.
Now Red Snake and Blue Snake live and play happily together - I hope your kids get as much enjoyment from this pattern as mine does.
