I use a lot of my scraps in swaps. this does not work if you need to make 12 identical blocks with the same fabric but more and more there are swaps you need to make 6 of the same pattern but they can be different colors. Here is one I am in right now

It calls for 6 blocks of the same pattern but they can be made with different fabrics. Here is a picture of my first set for this swap.
Above that are pictures of blocks I received back in a similar previous swap.
