Step 1: Parchment Roll
After cutting out the head and arm holes with utility scissors, cut through the armhole and roll self up in the rest of the the foam roll. Have an accomplice mark where the other shoulder hits. Then, fold over the foam to line up the existing arm hole with the mark. Trace though the arm and face holes, and along the original edge. Cut out the holes and the extraneous foam from the side.
