Zipper Slider with Pull Installation:

• Add all sliders at once and have them on the tape ready to go, or cut zipper lengths individually and add the pulls as you need them. 
• Open up 1 end of the zipper a few inches, it doesn't matter which end, it's a two-way zipper!
• Hold a zipper slider with pull in one hand, with the rounded side down, and slide one side of the zipper tape up into opening of the slider until it just catches inside. Grip this side of the tape and the slider now with 1 hand, holding them firmly together. 
• Slide the other side of the tape up, and into the slider. Firmly pull down the zipper pull.
