It is more difficult to quilt on a DSM with high loft batting. I would recommend Hobbs or Warm & Natural, they are thinner with the weight and loft of what most quilters use. Any pulling on your quilt will make the stitches uneven. Maminstl gives great advice on keeping the quilt supported. I had extra tables around my machine (two folding ones) that I would put up to quilt before I got a longarm. Good luck, welcome, and come back with questions anytime.
