I've done a King on my White machine and I had to just remember to keep it rolled up. I took the class on Craftsy for
doing large quilts on a home machines and she showed how to do in three's and cut the batting in 3 sections but when you cut curve it and then you can either tape the sections together or zig zag hand stitch back together and I'm going to try it on the quilt I'm going to do now it's a King and I think it'll make it easier. Hope this helps you a little. Sue
