I have a friend who has completed this quilt. She has a longarm and quilted the quilt with Hobbs 80/20 batting with no problems with the extra layers. She did not do much quilting in the "pre-quilted" blocks other than echoing the flowers, leaves, etc. I am currently working on my own and plan to use a GOOD grade polyester batting as her quilt was quite heavy. Other than that, the quilting shouldn't be a problem. One note - we both used Quilter's Dream 70/30 batting on the individual blocks which is fairly thin batting if you're not familiar with it. Good Luck!
