A better option on the backpack might be to make a paper mache flap that covers the top hole completly for the master and just mold it as a solid piece.
I have been a bit behind on listing all of the new parts that I have made molds for lately so I will start adding a few to the
list on page one, a few at a time.
I am adding the apartment Jengo snap on leg armor left and right pieces, the rots pistol and left and right clone commander holsters, the ROC Cobra Para viper helmet and goggles, and the new legacy concept snowtrooper nubbed helmet.
