When I first started hand quilting I was certainly not experienced in quilting specifically but I was an experienced hand crafter (needlepoint; embroidery; cross stitch, etc.) I jumped in feet first and don't regret it. I wasn't, however, working on a vintage pieced. I would agree with others to put together a practice sandwich and get a feel for it. Get to the point where your stitches are consistent - they don't need to be tiny, just consistent. Then move on to your vintage top. I think you'll be happier in long run.
