Long story short, I have no documentation. But I do have a pretty purse!
Now that that's out of the way :)
The completed purse! It's made from Purely Silks size E beading cord with size 15 rocailles by Miyuki of Japan. The pattern is essentially the knitted star bag I made earlier, only with six points instead of eight, and obviously much longer! The lacy section in the middle is k2tog, yo, repeat and p2tog, yo, repeat endlessly row after row. I'm a little sad that I didn't look at more patterns (I extended this one from a two row eyelet design on another bag) because the p2tog was rather brutal. But it's pretty, so oh well! The square end is closed with a three needle bind off as described here on Ravelry--post 46 in the thead-- which is a rather brilliant way of doing it.
I used adjustable toe rings for the rings, and they work perfectly. You need something quite small, which I found out when the size 6 rings I ordered didn't work. You also need something that won't catch on the beads and not go on, which attempt number four, small hematite rings did.
I did keep track of everything and will write it as a pattern, including directions on the fringe.
Here's how the purse works. There's a slit in the middle section, which is knit flat instead of in the round. To put something in one end, slide the rings to one side, put something in, slide one ring back, and voila! safely stored things!
And here that is on the other side.
And below are some detail pictures!
