I'm glad this is helping. Kim has tried to get Craig to put the instructions on the AS website, but he's super busy, and easily distracted.
I really think they'd sell more of them if it was clear how they were used. I'll bug him about it next time I see him.
For people that are struggling with chosing a size, I'll tell you that Kim makes BIG beads, so these are sized accordingly.
The medium is the most popular size, but keep in mind that these are basically for focals, so even a medium makes good sized beads.
