Beryl Tsang, a cancer survivor who lost her right breast to the disease, didn't like any of the prosthetic breasts available. So she knitted her own! Beryl posted the plans on Knitty.com or you can buy a set from her Titbits site. From Knitty.com:
I finished my first knitted titty an hour before the party and wore it with one of my favorite lacy underwires. When a friend, who had been following the whole titty saga, saw me she remarked, "You really did a great job! Your left breast looks almost as good as the right one -- a bit lumpy but very realistic."Link to Knitty.com, Link to Titbits.ca (via Bust)
"You know," I replied, "It was my right breast that was removed."
