I would suggest that you start with a log cabin pillow or table runner -- maybe 4 or nine patches. See how you like the process, and have something you can finish up relatively quickly. Then, if you love it, you are well equipped to go on to making the full quilt.
Log cabins are one of my favorites, and one of the few patterns I've made repeatedly, because they offer so much creative possibility. But they can be frustrating to make, specially for a beginner working on your own.
