That's awesome. I also, came to quilting late. But, was blessed to be taught the basics by my mom as well. We don't live in the same state, but, when we do get together, we still work on quilts together. Sometimes, I even teach her something. She gave me the love and basic knowledge. But, there are great online classes on craftsy and on you tube and blogs. (Sometimes they give updated very efficient ways to do some of the same things.) And sometimes, I just love doing it the "older" way. I find that my color placement is better. (I work on a lot of scrappy quilts.)
I hope you enjoy your time with your mom learning a new craft.
