Corpsing a Funkin Foam pumpkin.
I just got my hands on some Michaels fake pumpkins at 55% off and I am tempted to give this a shot. Thanks!If you're going to cover the pumpkin with "corpsin' stuff", why not use a fake pumpkin as a mold to make cheap papier mache ones to corpse?
Just cover one half of the pumpkin with papier mache at a time. Front/back, top/bottom, as long as you can pull the papier mache off when it's dry. Then do the other half. When you have the two dry halves, just stick them together with a few more strips of papier mache. Don't apply the mache too thick, or you'll lose the pumpkin shape. If you need to reinforce it or add depth to the cut out areas, that can easily be done later to the inside.
Just remember to use a release agent! A light coat of Vaseline, a thin layer of liquid dishsoap (washing up liquid) that you dry with a hair drier, or several coats of paste wax should work just fine. Watch for undercuts. If you have to make three or more pieces it'll still work.
I've been corpsin' for quite a few years now, and I'm moving towards lighter weight props lately. (Although latex, batting and a good ol' Bucky will probably always be my favorite!)
