Search for quilting on youtube. Then watch some videos to find something that strikes you as doable. Next, come back here, tell us what pattern you have chosen, and we will coach you through it. Also, do a google search for free quilt patterns. Welcome and enjoy the process. If you find yourself feeling stressed, stop over-thinking about it, and come here for more encouragement. Welcome to your new addiction, lol.
BTW - I can recommend Eleanor Burns patterns because she breaks everything down to step by step. That is how I started.
