I'm not sure exactly what "other parts" you're talking about. If you're having trouble with your dangles coming off the loop/eye, you can either make a wrapped loop (tutorials are easy to find on the internet) or you can slightly bend the loop into itself.
If you want to put beads above the loop, but on the actual hook part, just make sure the wire is bent far enough back over the bead before shaping the hook. Hope that helps!
The switch knot is a decorative lacy macrame/ hemp jewelry knot that helps you save on twine too. This tutorial shows you how to tie one with clear pictures and instructions.
A sliding knot is a wonderfully easy way to end off a leather, string, hemp, or corded necklace or bracelet. It looks neat and stylish, is a very practical closure, and is very easy to make.
