But not this time! I finally found a tutorial that shows the difference, at a website called Native American Beadwork. They describe peyote as being a "unit of two" stitch and gourd as being a "unit of three" stitch. You can see the difference in these two pictures from the website.

The Native American Beadwork website also offers some blank graph paper so that you can design your own patterns. There are two types - one with spirals descending to the right and one with spirals descending to the left. To get you started, here is a page at another website, Pow-Wows, that offers graphed patterns for some traditional designs.
I haven't used the stitch yet, but I have the tutorial on my "to-do" list, because I really want to give it a try.
