I was just looking at the purse you made. I think if you can do all that, you’ve got quilting in the bag 
.
I have never done any sort of fancy free motion quilting on my sewing machine, but I have done some straight line quilting on my I-Spy quilts. The most difficult issue I run into is the weight of the quilt. I try to combat it by keeping the bulk of the quilt on the table rather than letting it drape over the other side (I have also copied a ‘weightless quilter’ concept that is like a helping hand to hold the quilt so it doesn’t drape, but I’ve yet to try my setup). The quilting gloves also help because they give me a grip on the quilt rather than it just being slippery under my fingers as I run it under the machine. The other thing that helps me with straight line quilting (and I’m using that term loosely, because I can’t sew a straight line to save my life) is a walking foot.
If you’re interested in doing free motion quilting, here is a helpful diagram and information on how @MistressJennie does hers and here is a post with FMQ tips and tricks.
For either free motion quilting or long arm quilting (without a computerized component), there are also fabric panels that you can purchase that have quilt designs printed on them so that you can learn and practice various free motion designs. Or, another product that I just came across is tear away quilting paper that you can get in a variety of designs. You baste the paper to the top of the quilt, quilt over the design, tear away the paper, and voila! you’ve quilted your quilt!
