i do if it is something new- a new technique- something i'm just not sure about- those practice blocks come in handy later
you can use them for small projects (the front of a tote bag, a pot holder, something to practice a quilting design on) or make a sampler quilt out of them later- when i find i have many that i doubt i will use for anything i pass them on to someone else who will put them to use...practice blocks saves lots of good fabric- and frustration
