Now I've traced the patterns onto a sheet of half inch foam. Just like I would for fabric, I'm placing my patterns close together and near the edge of the sheet. By doing this I'm not wasting a lot of foam.
Use an exacto knife with a sharp blade to cut your foam. This will give you a cleaner and more even cut than you would get by using scissors. Remember to use caution: Cut on a sturdy surface, and cut away from yourself.
Now I have all the foam shapes I'll need to make the cats head.
