My open tailed sling is about 30″ across. I wish to add a pocket to it that when flipped inside out can be stuffed with the sling and zipped shut.
– Reversible zipper: My Joann’s only had the super industrial looking one. I will have to hunt for a more appropriate size the next time I do this.
– matching/contrasting fabric and thread: I used left overs from making my sling and a matching fabric.
