I think the Missouri Star Quilt Co is a good place to start. The owner Jenny Donn specializes in precut fabrics grouped together in "collections" (40 different fabrics that go along with one another without you having to pick each fabric out one at a time.) She has also simplified patterns to use these precuts and has made many, many you tubes to show you how to make many simple quilts. Now she has a new program where you buy the kit, put it together, send it back to her where she quilts it for you and returns it back to you done. She is trying very hard to get new people to start quilting. This is at the opposite end of the spectrum from your mom's skill level, but a great place to start.
