A nine patch is the way to go. They are easy and they teach you to match corners. and you can separate each block with a white block to make it go together faster. I took a sampler class for my second quilt and I learned so many things and different methods, but you can just dive into some of the simpler quilts on your own and do fine. Be sure to read the directions through and then maybe make a practice block of what ever you decide.
Another good one is Warm Wishes, google it for the directions. Good luck and have fun.
