@fdenton05 Handmadelenin on YouTube has a video in which she explains how to make a bookmark hole and there are also videos by other people who explain how to make tassels. If you search for "friendship bracelet bookmarks" you should find the videos.
@coyoteflow thank you! I made sure to make every row the same width of the previous row and try and make every knot as perfect as I could get it to be. If a row wasn’t the same width as the last one, I would either stretch it slightly or gently push the edges in to keep it straight.
