Put them aside for now. I gather you are adventurous in trying new patterns. Each time you try some new patterns you can put a block aside and when you have amassed enough blocks, sew all your "testers" together into a quilt. Now you'll have a record of your experimental works - those you used and those you did not, and a record of how you have accomplished your good works and the testing you had to go through to get to a favorable and satisfactory outcome. I love to see how people come to get a design to their liking. Keep it up.
