Step 9: Curtain tape - gathering
The curtain tape now needs to be pulled to gather the curtains. Each piece of tape has two strings running through it - at one end, pull the strings a little bit, and tie them together.
At the other end, pull the strings out, tie them together, and keep pulling. Distribute the curtain material evenly so it's not bunched up at just one spot, until the curtain is the width that you want it - don't make them too narrow or they won't close all the way. Tie the other end off with a loop, so that you can adjust later if necessary.
