Sandwich zipper w/fabric FACES together & sew across (see pins).
Use zipper foot to sew & move zipper head away from needle. Make sure needle is down into fabric when zipper foot is released to move zipper head away.
Should look like this so far.
Fold like above w/fabric BACKS together.
Add remaining STRIPE FACES together & SOLID FACES together. Sew across top (see pins).
Should be layered like this.
Optional: Sew again from zipper face creates cleaner look. See next image for comparison.
Right side looks cleaner.
