Use these zipper pulls with Sallie Tomato Zippers by the Yard, or any size #5 nylon coil zipper. This size zipper is best used on the top of handbags, backpacks, totes, laptop carriers, and more!  Make single or double slide zippers with these pulls.  Double slide zippers open from the middle out, which is ideal for luggage style bags, bowler bags, handbags, and more. Instructions: You can easily attach the pulls as needed by simply sliding the rounded end (with two openings) onto the end of the tape.  Do this by inserting each side of the zipper chain into each side of the pull, and carefully lining up the ends so they are even.  Then, slide the pull onto the tape.  I recommend to mark the desired length of your zipper, then stay stitch each end before cutting. Zippers by the yard are very easy to use, so please don't be discouraged if your coil doesn't line up perfectly on the first try!  With a bit of practice, you'll realize just how easy they are to use!
