Fix a broken zipper pull: 1) Choose the color (yeey!) and cut a 10 centimeter length of the ribbon. 2) Pull it through the zipper slider so it's exactly half way through. 3) Sew the two ends together as seen on the photo, two or three times. Use a very dense zigzag stitch. Make the seams thick and bulky on purpose, as this will ensure that it stays nicely between the finger and the thumb when zipping and unzipping the jacket.
