Use expanding foam from the hardware store to stuff the dress-form.That stuff hardens well enough you will never have to re-stuff it, but still ok with pins, etc. To lessen volume, first stuff with packing peanuts or crumpled newspaper. Be careful to keep the body doubles' shape the same while the foam expands. Working with small sections at a time should help.
I like that this pattern goes flat against the chest between the breasts, I've seen a lot of uni-boob dress forms and this tutorial is great!
Make a dress form that is the exact replica of your body... with duct tape! Mad in Crafts..........This is the best one of all the tutorials out there about making a dress form from duct tape. The other ones that I have seen involved way too much mess and danger to your physical being. This is genius ...wear an extra long teeshirt tape it up then take it off.
Wanting to make a Dressform so just getting idea's so I can come up with a design using wire and paper mache... or other mediums.
