Now that your four strips are quilted and the threads are buried or taken care of somehow, you’re ready to start sewing the strips together.

Lay them out in a windmill shape. I lay mine out with the lining down. I want to see how the outside lines up when I stitch.

Sew two strips together by butting them up against each other and using a zig-zag stitch, then the other two. Lastly join those two pieces together.

Sew the strips together starting at the bottom of the bag. Take care to get the sides snug up against each other and make sure the zig-zag stitch bites into each strip.
