Please don't ask where I got this info. Several years ago I met a CD that told me he made his own breast forms. He explained the whole process. Then, not long ago I exchanged some mails with a dresser and he sent me this "formula". It is the same method. The breasts are quite realistic and have the heft and bounce of real breasts. I hope I don't get into trouble here for leaving the phone numbers in.
Go to your local artists supply shop and buy some modelers clay, also known as plasticene.
Shape this into the size and shape of breasts you want.
Next make a mold of your breasts by pouring artists molding material (Hydrocal) over your clay breast forms. When the Hydrocal has dried, carefully remove the molds from the clay breast forms. The breasts forms themselves are made from a material called Plastisol. It is also known as Hot Melt Vinyl or as Fishing Lure Compound. It is the same stuff that is used to make those squishy fishing lures and soft, wiggly children's worms. It simulates a breast quite well. Pour the very hot Plastisol into the breast molds and let cool for at least six hours.
Excellent booklets that will answer every question you can think of, on all aspects of moldmaking, casting, and where to obtain various supplies can be obtained from Castcraft, Box 17000, Memphis, TN 38187. Cost for these booklets was $39.00 several years ago. Probably a lot more now with higher oil prices. The Plastisol can be purchased from Pro Am Products. Cost $11.00 per quart or about $34.00 /gal. You should also consider getting a couple of 1/2 oz tubes of flesh colored pigment. (#17 in the pigment colors) Other Plastisol vendors are Hilts Molds, Jann's Sportsmans Supplies, Industrial Arts Supply Co. Most of these suppliers have catalogs, some free, some charge a dollar or two.
