The last quilt I made was glued front, batt and backing. When I put that on my DSM for quilting, that puts a lot of pressure on the edges and sometimes they come apart before you get there. So the best thing is to sew around the outside to hold everything together. When it is all glued, it handles like one layer of fabric. So why not put the binding on then?
I did just that. I put the binding on before I started quilting.
Worked very well.
