Quilting a quilt is not for everyone.
I would start by making a sandwich (12" square) and practice quilting on that. If you like what you're doing, then go onto bigger things. If not, you may want to send your quilts out to be quilted. I don't mind doing the quilting, but I absolutely don't like doing the binding - I can do the front by machine, it's the back side by hand I don't like doing. Instead, I trade with a friend to do mine.
You may find that you don't like doing the quilting part at all. It can be very intimidating. Only practice will let you know. Wishing you luck as you try with a practice piece! {{{hugs}}}
