Pins--I have strip of mole foam (the stuff you put on your feet) stuck to the side of my sewing machine, as I take a pin out it gets stuck into the foam. Works for me and I don't have to worry about pins in my mouth.
Ps be sure its mole foam not mole skin.
Re sticking pins in clothing. Years ago had a home ec teacher that had had a mastectomy. She would freak out all the new pupils by taking out the pins as she sewed and sticking them into her boob. I guess they were made out of foam or something back then, but I still remember her doing that and about fainting. grin. At least she taught us to have a sense of humor if life tossed one lemons.
