My favorite part of making a quilt is designing. Improv keeps the designing going until the quilt is pieced and quilted. Most are small, less than 10x16. So there's not a lot of fabric investment (although my stash will last longer than my lifetime). Time.... well that depends upon how long I enjoy working on it. If it's going smoothly, it can take 2-3 hours. If it's not going well-it's time for a break until maybe next week. This is suppose to be fun, so if it's total frustration, I may cut it up in little pieces for dog bed stuffing.
