There are many many beginner books out there, and there are even lots that have easy and attractive projects to create. Quick & Easy Stitched Jewelry, written by Cathy Jakicic and published by Kalmbach, has a bit of a bonus feature though. Cathy has generously designated all of the projects in this book as royalty-free. Not only can you make them for yourself or as gifts for others, but she encourages you to sell them if you wish.
Rather than concentrating on just one stitch, this collection gives you ideas for many...peyote, square, ladder, herringbone, RAW, and bead embroidery. Plus, there are instructions for the basic wirework you will need for constructing the finished pieces.
