Space Invaders Bracelet

I have recently bought beading loom - it was really cheap and I couldn't stop myself - and during the past few days I had a crack at it.

The choice of pattern for my first project was quite obvious. As an old geek, friend of geeks and a geek fiancé I was obliged by geek law to start 0with space invaders (if I had more colors, it would have to be old school Mario Bros).

So, with the pattern in mind and the instructions from The Encyclopedia of Beading Techniques in my hand, I was off to a great start. The beginning was very easy and the pattern showed immediately. And I was doing a very good job all the way until I managed to tangle the beading thread and had to cut and reattach it. Which in turn caused some nasty knots on the side of the bracelet - well, I guess this means that I will wear it, rather then sell it in my etsy shop.

Beading on a loom turned out to be a great technique. Very simple and effective. It is easy to introduce the pattern and control it while beading.

And it would be an amazing way of creating jewelery, if not the problem of ending the project. I find it incredibly difficult to find fasteners that would fit beading bracelet. Any gold, silver or metal in general is too heavy for minute beads and beaded endings seem unreliable.

This time I stick to simply knotting the threads, once the bracelet is on my wrist. I think it looks very well and fits the style of this bracelet but I am not sure if it is "professional" enough. So I am still on a quest for better solution. Anyone has some ideas?
