Hello! You can also find step by step tutorials on the About.com Beadwork site. If you look at the homepage for Beadwork and then look down on the left hand side, you'll see a link to
Beading Stitch Tutorials - there are all sorts of tutorials for flat and tubular peyote stitch, and I am always updating them with variations on the stitch like increases and decreases, etc. There are also tutorials for brick stitch and herringbone stitch, netting, and some new ones in the works for right angle weave and chevron stitch.
Good luck and welcome to the forums!
