I don't use any at all, don't even have one in the house! I not only have three kids that would have hayday with a pin cushion but I also have two cats that would just love to get their mouths around a pin I am sure, exp. if I stuck one in there with thread in it! So I keep my pins in the container that they came in that I can put the lid back on. Its little and portable so I grab and go anywhere in the house I need to be!
