There are, as you can see from the above comments, many sources of quilting designs. I like stencils quite well. I also have several books with designs. Many quilting magazines have design columns. I would also suggest a blog site, Inbox Jaunt, by Lori Kennedy. She does tutorials about sketching and then doing quilting motifs in a step by step fashion. All of her designs are available on the site. She also has a Craftsy class. I personally am inspired by her blog-in lots of ways.
