Your quilt is beautiful. I find it amazing when I show my quilts to my family and friends and they do not even look at the quilting itself but they see the whole quilt (colors, pattern etc...) You are looking at your quilting with a "magnifying glass" others will not. I would just go ahead and practice all you want. there were excellent suggestion given above.
What I use is 2 pieces of "non-adhesive shelf and drawer liner" that I cut about the size of my hand... because I did not know if I would like or even be able to quilt a big quilt with my DSM and I did not want to invest in gloves that I might use once only.... that is what I still use
