Piecing batting is one of my least favorite things to do but I’m frugal enough that I do it. Sometimes I grab a couple larger sections and piece these by hand downstairs in the longarm room but when I’m going to piece multiple battings, it’s quickest to do them by machine.
I start with reasonably straight edges and setting my machine on the widest zig-zag possible, I feed two pieces through stopping frequently to adjust them so I don’t stretch them out of shape.

Here I’m adding a 3rd piece and notice I always sew with the narrowest piece under the arm of the machine.
In just about an hour and a half, I’ve got 5 battings pieced – all of them 74-80 inches long. You can see the the top batting is thinner — that’s pieced from Warm and Natural. When I’m piecing, I do make sure I piece the same type of batting together. The bottom four are Hobbs 80/20 which is the batting I use most frequently.
I tend to buy my batting on the roll rather than by the package and I think that makes it easier to use almost every bit of it. For those of you doing charity quilts you might want to check with some longarm quilters in your area to see if they’d be willing to save batting leftovers for you.
