The question is: How much quilting is too much, FOR YOU. Quilting density is in the eye of the beholder. A finished quilt may have not enough quilting for some folks, too much for others and just enough for the maker. The quilting community is made up of folks with different tastes, so for your quilts, just add enough for you, and if you are having your quilts quilted, make sure you convey this info to the quilter. Just remember to read the label on the batting package and follow the manufacturer's instructions for the minimum required.
