I just finished a set of tea towels that doesn't have a fringe. Is there a video that talks about how to finish a fringeless product? I think when I started weaving I just started weaving after spreading the warp, no hem stitch. So do I just... stop weaving? How do I cut it off the warp?

Also, what do I do about all the little strings hanging off my towel from when i changed bobbins? Do i wait until after washing?
