1 yard 60 wide fake fur
1/4 yard pink felt
2 2 pieces of sticky back velcro
Step 1: Measure Roomba
Step 2: Make patterns
When I was making the mouse, I didn't bother with making patterns for the top and sides at all - I just drew and cut directly from the Roomba itself (see Step 3).
Cut whatever pieces you've made out of whatever kind of paper you're using.
