<human>:  How do I fix a broken zip off my coat?
<bot>: Start by gathering the supplies you'll need, such as a needle, thread, scissors, and a seam ripper. 2 Next, use the seam ripper to carefully remove the existing stitching around the zipper. 3 Unzip the zipper, then use the needle and thread to attach the sides of the zipper to the fabric.4 Lastly, re-zip the zipper and test it out to make sure it is working properly.
