In the above picture I showed that for me to get around the zipper, I zip or unzip so I don’t have to deal with that pesky hump of the zipper to go over.
Stitch down that zipper and then lay your first liner piece right on top and stitch again.
All nice and neat.
When you put it together and turn it right side out it will be nice and neat!
Now you can do this the right and proper way and do a nice stitch to make it invisible… but
I just zip a stitch right down the side so it encloses that opening.
Push your liner back inside the pouch.
