If you have long been using or dealing with zippers, you surely know the importance of choosing the right zipper for whatever sewing project you have in mind. After all, zippers are not just mere accessories as they can also affect the final product depending on how you choose to use them.
What to Consider When Choosing Zipper Lengths?
Most zippers are sized in lengths with 2-inch intervals. The length indicated on the zipper’s packaging refers to the length of the zipper itself and not necessarily the length of the cloth tape where the zipper is attached to. For instance, if you are planning to design a bag, you need an opening that is longer than the length of the zipper to give way for the required space at the zipper’s tips.
If you check the package of your new zippers or the zippers that you want to replace, one thing you will notice is that the length of the replacement zipper is not exactly the same. Your best option here is to shorten a non-separating zipper so you can use it accordingly.
To shorten a separating zipper, turn over the top of the zipper then trim in the area for seam allowance. The separating zipper’s bottom part should be kept intact to let it close and open as needed.
Take a look at the common types of zippers to know more about their differences.
