I could use some help figureing out how to store some of our masks.  We have lots of stuffing and that works fine for some of the less costly masks.  Our problem is we don't have enough head shaped, foam stands for the higher end masks.  Does any one have any ideas what I could use instead.  Stuffing them doesn't work well as they loose their shape and have to be reformed constantly.  I would greatly appreciate any ideas you all may have.  Thanks!

You could try empty milk jugs maybe, this is what i use for making my figures for halloween.

Coffee cans or old cans of paint would work also

If you have access to cardboard boxes i'll make a template for diy stands. we uused them at the halloween store and i grabbed  bunch of them before they closed. they work great and cost nothing but time.

Thanks for the great ideas.  I appreciate it lots.

If you want them to last, clean them on the inside with a damp/soapy sponge.
(Sweat, oil from actors skin, direct sunlight will just destroy store bought masks.)
Then give the insides of the masks a light dusting with powder, baby, talc etc...
Stuff them to their natural shape with shopping bags and place on whatever makeshift stand you like, ie; 2 liter soda bottles.

One thing I did in my shop was to take an old wooden ladder, take one of long sides off.. and boom! Instant mask stands!
