Yes, there is a wealth of info on the web, including some video on youtube. Here is a picture of one I did yesterday with just mokume, and I folded the tank vertically front and back:
I did the stitching vertically as well, which made the woodgrain horizontal. I like this better, design-wise.
BTW, did I mention I was using dental floss to create the stitching? It's easier to see to remove than thread because it doesn't bond with the dye. And it's strong enough to allow me to really pack the gathers tightly. Try it!
