Breastforms for small $$$
Check out www.truekare.com. They have a section of irregulars and imperfects. Several sizes to choose from, and with shipping will not send your purse into cardiac arrest. This is a personal expirence recomendation.:D
Waterballoons and breastforms
Before I really got into CDing, but after the "socks in a bra" stage, I made my own. Waterballoons covered with Home Depot almond silicone. I developed a technique where they dried smooth and put nipples on afterwards. Made several sizes. Still have one big set around. The weight was rite, but not the texture or feel. I just purchased some huge #13's. Nothing like the incredible weight, bounce, and feel of those $$$ silicone babies!
