I made a denim quilt and used zips from jeans to create a couple of pockets. I used the quilt as you go method and put the zips on before I sewed the blocks together. i also put an extra layer of fabric on the fabric side just to make that side stronger. This quilt was for my father inlaw and the pockets were for keys, wallet, phone etc. Even though I had never put zips in before and just winged it they turned out pretty well.
