Basting Quilt Back onto Leaders for Using Zippers on my Longarm

I've been asked how I sew my zipper leaders onto my quilt backs. It's super simple, but a picture paints a thousand words, so here it is. I mark the center of the quilt back with a pin on both top and bottom (or both sides if putting it on the frame sideways).

Lining up the center of the leader with the center pin, I begin basting the two together, lining up the edge of the backing fabric with inside edge of the seam allowance. My preference is to use a medium width and largest length zigzag stitch and the cheepest thread I have because I think it comes out easier.

When done with the first side, I turn it around, return to the middle and sew to the other edge. Repeat on the other side. After that, I can zip the leaders onto the zippers I sewed on my longarm, making putting the quilt on and taking it off a breeze.
