You definitely don't have to use your squares on point to make an interesting pattern. Depending on the amount of contrast you have, you can use color/pattern to create additional shapes just by planning out which squares you place where, or you can go for a completely random / scrappy look. The joy of the charm pack is that you know all the colors are going to play nicely together. We're all looking forward to seeing what you create - I'm sure it's going to be great!
