I mentioned in this post that I was working on tutorials for Zippers Poppers and Snappers.I'll be posting a series of tutorials on how I use zippers and how to attach them to bags. Hope you find it useful.
When I was doing some research for these tutorials I discovered some trivia about zippers or zips (a device used to join two edges of fabric)
The main types of Zippers are
Coil
Metallic
Invisible
Plastic
Open ended
Close ended
Here's an interesting image of an earlier form of the zipper designed by Whitcomb Judson called the 'Clasp Locker' ( Scroll down the page to find the image)
The modern Zipper was designed in 1913 by a scientist called Gideon Sundback and was originally called the 'hookless fastner'. It was coined Zipper in 1923 and was originally used on tobacco pouches and boots.
Enough of the boring stuff.... here's the cool stuff
For the tutorials I use the coil zippers ( I only found out what they're called while I was doing the research for this tutorial )
Lengthening and shortening your Zippers
Zippers don't always come the exact length you want for your project. That can be rectified by lengthening or shortening them
Shortening Zippers:
I usually do this by hand although you can use your machine for this.
To shorten by hand
- Close the Zipper and measure it to the length you want. (Measure from the zipper teeth)
- Whipstitch across the coil in the same position about 10 to 12 times with a doubled thread
- Cut the Zipper about 1/2" below the stitches
- Measure the length of the opening for where you want to insert your zipper for example 12"(add any seam allowances )
- Measure the length of the zipper teeth. In this case its 8"
- Cut a piece from your chosen outer fabric to the width of the zipper and however long you want to extend your zipper by( I'm extending mine by 4" to make 12") then add about 1" to the length for the seam allowance.(My fabric is cut to 5". 4" + 1" seam allowance) If you're lining your bag cut the lining fabric to the same measurements
- Cut the tabs in half ( Two 2 1/2"tabs outer fabric and two 2 1/2" tabs lining fabric)
- Measure your tab 1/2" in from the short outer edge. Fold and press wrong sides facing. Do this for the other three tabs.
- Sandwich your Zipper between the fabrics like this and pin in place. Alternately use a bit of fabric glue
- Sew a few mm from tab edges
- Game Set and Match extended Zipper
Machine method
Here's instructions on shortening your zipper using your sewing machine. With coil zippers I don't bother with pulling out the teeth I just cut it about 1/2" below the tack stitch
Lengthening Zippers
To lengthen your Zippers you need to add tabs to each end to extend them. Here's how I do it
