That gives me some ideas about things around the house I probably have. I have a medium sized quilted tote and I remembered that I have a bunch of 1" high and 2 1/2" round plastic cases with a screw-on lid that I was saving for my granddaughter to just put stuff in (like little and BIG girls like to do). They are empty containers of mineral powder foundation (makeup). Those are pefect for pins and the lids won't accidentally come off.
