My wife made my boobs for me. We went to a dressmaking shop & bought 2 pre-formed shapes that are sewn into the bust of a dress(I don't know what they're called). She sewed a piece of material on the back of them, leaving a small gap, filled them with bird seed through the gap & then sewed up the gap. Gave herself a "pat on the back" afterwards too, by telling me I had great boobs!
