To help in interpreting some of the wonderful stitches I found on the web, I made myself some graph paper. Here are some of the ones I use.
If you have trouble printing any of these images, right click on the graph, select Save Image as, and then select a directory on your PC. You can then open and print in any print shop/paint type program.
African Net Graph
You can see examples of the African Net stitch here. I found the instructions for the stitch on the about.com beading site hosted by Emily Hackbarth.
Heirloom Lace
You can find my interpretations of Heirloom Lace here. I found the instructions for this stitch on the Bead and Button web site.
