Donna,
I buy all of my buttons at flea markets. I know that soesn't help you for right now, but something to think about for next spring and summer. Some are very pricey now, but you can still, on a good day, find a mason jar full for $2. I love buttons and have zillions of them because I use them on sachets that I make. I would love to see your pincushions too because I have been thinking about making some! Post photos soon!!
