Thank you!
The bowstring is just a piece of thread. I cut off a bit, leaving enough to wrap around. First, I used super glue to attach both ends to the bow. Then, I had to wait for it to dry, but since I am severely impatient I went on with step two too soon, and added another drop of superglue to the ends and wrap the loose ends around three times.
It is best to use a tweezer for that, but I was too lazy to get up so I used my fingers... Not smart... Anyways, I cut off the remaining loose ends and that was that. Perfect bowstrings. I am sure there are better methods out there, but I always make do with what I have. Jennifer's example picture shows probably a better way to do it, but whatevz...
