Make a Zipper

For many of my patterns, custom size zippers don't fit. Rather than limit myself to the manufactured lengths, I learned long ago how to adjust. Most zippers can be sewn right through. For thicker or metal zippers, the technique I'm going to show works just as well. Simply skip sewing through the teeth and leave a longer tail inside the tab.
Step one:

 

Cut the zipper just a little smaller than your project (or you can cut it the same size if you wish. For my project, I wanted the finished ends of the tab to show.

 

Step two: cut 4 tabs the width of the zipper and long enough to stick out past the edge of your project (trim the ends when you are finished)

Step three: line up two tabs with the zipper in the middle. Sew across the end several times. If you are using a thicker zipper, lift the needle across the teeth. If you have a good amount of teeth past the seam, the tab will stop the zipper pull from running off the end.

 

Running back and forth. One end (the top probably) will be open. Hold the teeth as close together and as flat as you can and continue as before.

 

Step four: open tab, smooth flat and sew either the sides or the bottom edge (close to the end so it doesn't show in the final seam)

 

There you have a zipper of any length, ready to install. For the next blog entry, I'll use this zipper in a pencil case style pouch.
