I'm a relatively new bubble-maker but so far have had great results using the Basic Mix recipe. I'm currently experimenting to see how my hard-water at home affects sludge formation in guar gum based juices. You can follow my progress in my blog, if you're into that kind of thing.
I've built two tri-string wands, both using the tri-string guide, the second using a clip-based mechanism similar to some of those seen around the forum.
Hope to start contributing to the wiki and making even better bubbles soon!
