I have bought small wallets for business cards. They have about 10 wallets in each. I have a card to which I have stapled a piece fo fabric that I have made a garment from. I write on the back a description of garment made. I also have one for stash fabrics. I keep these in my bag and then when I am shopping I can match fabrics, thread or buttons etc or even accessories. You never know when you might see something you need or want to match up. I got the wallets from an office supplies store. Ther are different sizes but you need a size that is easy to carry.
