I come from a many years of garment construction, and how I feel is that quilting is simply fun and creative. No matter what I make, someone will love it and I don't have to worry if it's going to fit them (or me) or not.
I get to play with lots of colors of fabric, and it's all 100% woven cotton which in my mind is the simplest fabric of all to use.
Quilts are my creative outlet. I often design my own layouts and figure it all out. I liked doing that with garment construction, but that is a lot more work and the end result is a lot more questionable. With quilts, since it's all pieces, adding another if you got a measure wrong is no big deal!
BTW - there are many people on this board that have a decent amount of experience in garment construction, so if you ask a question about that, you'll probably get advice too. Just be willing to get sucked into Quilting because you're going to be seeing a lot of pictures of beautiful quilts and it won't take long before you are going to want to make one yourself.
