@Musicman32 for alpha bracelets, the easiest way is to just make braids with the base strings at the ends.
If you have a general question like this, I highly recommend asking it on the forum, because the comments on a pattern are less likely to be seen by someone who isn't the creator of the pattern or a moderator reviewing your comment.
@slim51999 To understand how to make knots and read patterns, watch the 2 video tutorials near the top part of this page- located between the pattern preview and the knot structure diagram. You can also go to YouTube and search "alpha bracelet tutorial" or "how to make alpha bracelets."
