I have only used Minkee once on my longarm - it was a childs quilt - but don't remember the size - I did not use batting and I am glad I didn't - it was heavy enough without - anyway - I did a large meander all over the quilt and I was pleasantly surprised how easy it was and looked nice on back. I don't think I would densely quilt with Minkee - I just don't think it would look good. BTW it was cotton on front - Minkee on the back and I used cotton thread.
