I float all my tops,
I tried using the rollers and somehow got things all wonky. I do much better floating. Now that is with my throw sized quilts, havent tried it on a bigger one.
And if you dont have them yet, definitely invest in some snappers
I can load a backing on my frame in 10mins with zero pins. Think the ones I got were $75, best money I ever spent!
Quilt is gorgeous too
