I agree with an earlier poster, fat quarters, charms, and layer cakes even jelly rolls will get you the variety you need to work with these patterns. Dont overlook thrift shops as sources of fabrics or even clothing that can be cut up. I worked on a log cabin for my son for Christmas and used denim as well as a couple of his old shirts that were primarily blue plaids and checks to round out my blocks. Have fun and don't stress!
