One of the most important things to learn when making beaded jewelry is how to tie knots. There is nothing worse than spending so much time on a project only to have it fall apart! I have had it happen with my earlier work. Even one of my favorite fringe necklaces came apart.
There a plenty of sites (and the people behind them) that have taken the time to show us how to make a proper knot.
Here is a sample:
Knotting Between Beads – (Often done with pearls)
How to Tie a Double Half-Hitch Knot
Tying Knots and Adding Thread in the Middle of a Project.
You can find more free tutorials for bead and jewelry making on my other page here or by clicking the link at the top of my page.
Enjoy! 
Thanks for the like on my Bead feed post. what a nice site. Thanks for your generosity in sharing things. I will check back here from time to time, looks really interesting.
Thanks for the comment and for dropping by. Your beaded necklace is gorgeous!
I did read about you being a knot expert. I sure could have used your advice years ago when my jewelry never stayed together.
