Basically we just bought a small piece of plywood and a board. We made legs, nailed them on and painted it red. Then we screwed colourful bowls on it.

I found this idea on Pinterest, and expanded upon it! The "wooden" snowman was designed by me, cut out by my co-teacher's dad and then painted and decorated by me. We used it as a bean bag toss at our school's winter festival. I made "snowballs" out of blue flannel and rice. It was a BIG hit with all the children!
