Mini Pin Cushion Jars

Eight years ago I was working at the Holiday Inn in Memphis, Tennessee. I delivered room service during the week and bartended on the weekends. Everyone who ordered a sandwich for room service got a tiny little jar of mayo, a tiny little jar of mustard, and a mini jar of ketchup. I loved those tiny little jars and I would often rinse them out and bring them home. They were stored in boxes and hauled to several new apartments, back here to Nebraska, a few more houses, a storage unit, and then to our new house where they we promptly stored in the basement with everything else. I brought a box of them up this weekend, one of the treasures found while cleaning.
A milk jug cap was the perfect size for a pin cushion for the lid, I have attached it permanently to the metal lid with a brad.The pin cushion will, of course, be embellished more (rick rack!!!) and the metal lid will be painted. This color combo reminds me of cotton candy, which then makes me think of the circus, so I will be painting “big top” stripes on the lid. (Yes, that is exactly how my brain works!)
Fill the jar with buttons, safety pins, and thread card, add some more pins and a needle to the pin cushion and it’s a mini sewing kit, wouldn’t it make a great gift?
I have a lot of these little jars, anyone have any ideas on what else I can do with them?
