We started with a 4-inch wide headband. I like to use a paper clip to close it up, because young kids tend to take them frequently off and on. The paperclip gives the headband some give.
Then I added yellow and green circles for his eyes and purple antennae. I think that it ended up looking cute and can't wait to see all of our little "caterpillars". Stop by next week for more info from the program.
