Paint Chips! What's not to love? Every colour in the rainbow and then some - and - they give them to you. In fact, they encourage you to take them. So how can you not indulge on every trip to Home Depot or Ace Hardware.
I started my collection when we bought our house and decided we needed a total of 17 different colours throughout - and I haven't stopped since. Great in art journals, altered books, assemblage or just when you need to see a couple of shades next to each other to get an idea . Paint Chips, one of my cheaper vices!
