Knotting... Suggestions?

I was just wondering if people have suggestions for knotting. Especially with seed beads and working on looms. I don't know why, but I seem to be very challenged when dealing with knots, especially with multiple strands, such as on a loom. With just a simple, one strand seed bead necklace, I knot several times, even in the middle of the project, just because I'm paranoid of it coming loose everywhere. Only problem with that is if its a spur of the moment project, I can't undo it and fix my mistakes because I've knotted everything so much! Haha Just wondering if anyone had any tips or tricks to hand out. I seem to play with my beads and fixings more than making anything. I'll post a pic of a bracelet I'm very proud of though, and let me know what you think, and what you think it would be worth to you. I'm thinking of selling some stuff, and was curious about pricing. Thanks! Jami
