Needlecrafter has a nice way of presenting embroidery stitches. The section is called Stitch Dictionary and is literally that. Everything is divided up alphabetically with word definitions and in some instances a potted history. A little eyeglass takes you to a black and white drawing of how to do each stitch e.g. Chevron Stitch - A primary embroidery stitch worked from left to right along parallel lines. Rows of Chevron Stitch can be stacked to make an attractive border or filling. http://www.needlecrafter.com/Stitches/stitches.html
So if you are on the go a lot and learning embroidery why not print out a stitch or two to take along with you.
