Step 1: Cut Off More Than You Need
Step 2: Make End Tapes
From the end you have just cut, snip down the sides and across to remove about 1cm of the teeth.
Step 3: Attach the Puller
Feed the teeth from one side into the puller.
Zip it on just a little bit.
Carefully feed in the other side of the zip.
Hold on to the tapes you created and pull the zip down.
Step 4: Finish Off
Snip off the ends to the correct size.
