Every since I started sewing when I was young, whenever a needle or pin got stubborn on going in the fabric, I always stroked it through my hair and it would work great after that. Someone once told me she had seen her grandmother do that when she saw me do it. I told her the oil lubricated the pin to make it easier to push into fabric. Sure beats having a bar of soap around. I know where my hair is, but that bar of soap can get lost so easily.
