I don't have a zipper foot but I'd like to sew some things that require a zip. What to do? I turned to Youtube! There are a few videos explaining how to sew in a zip without a zipper foot. I watched them and fell in love with one online seamstress.
Anyways, I watched her video a few times. Then I incorporated an idea from and other online seamstress. The whole zip went in perfectly but for the part with the idea from the other seamstress.
Here are some photos. The part at the top was a stupid idea from a different video, and the consistent bottom was from my favourite seamstress. I just sewed this zip into a spare piece of fabric so I won't bother correcting it, but now I am confident that I could sew a zip in if necessary.
