In this blog, I will demonstrate how to use the coil zipper chain.
(Note: this is an updated post from the original)
To demonstrate I used 20inches of zipper coil and one pin-lock zipper head.
When using the zipper coil the first thing to figure out is the length of zipper you will need. For example, if I were making an 18 inch square pillow with zipper, I would cut a 20 inch length of zipper coil.
The best way to slide on the zipper head is to place it on a hard surface. While holding down the zipper coil with two fingers on my right hand I pull the zipper slider or head with my left hand. You can also do this by holding the two sides with a set of needle nose pliers.
While not shown, if your project requires a double zipper that opens from both ends (such as a lunch bag), simply repeat the procedure on the opposite end. Make sure to pull evenly so as to avoid a gap where the zippers meet. If you do create a small gap, advance both zippers to one end, separate the halves at the end without taking the pulls off, and gently work the gap out by pulling the gapped side backwards through the pull. Just be patient and take your time.
