So... I'm sitting in the Doctor's office waiting room w/mom (I was her ride) and knitting. Well, my yarn ball was small enough that it didn't weigh enough to stay in the bag and kept jumping out and rolling across the floor. Finally without even thinking about it I snatched up the ball and dropped it where it wouldn't come out. (Where you might ask...?) Right down the front of my shirt and into my bra.
a few minutes later, I realized what I had done and just cracked up laughing.
So YKYACW you use your bra/shirt as a spot to hold your ball of yarn.
