I got a Bailey some time ago and found it's not as easy as it looks. Time, lots of practice, and more time and I am still learning, but I love it. I will never quilt for anyone else, but I didnt intend to.
I am into a number of classes from Craftsy & they are wonderful. Again, I find I have to practice alot.
I wouldn't recommend starting with a large piece or anything you treasure. I did table runners and placemats then a couple of dog blankets. Come to think of it, I think the mats turned into dog blankets too!
Like Nike, just do it. Mess up a lot with no fear. No one has to see it. Better than looking at a machine and feeling guilty. Go for it
