Even with the limited number of options I used, you can produce 31 different structures with 4-hole tablets. Most of these have never been seen in the archaeological and ethnographic material, and may not ever have been woven by anyone other than me.
Tablet weaving is a fascinating and complex craft. Even basic structural knowledge can improve your understanding and enjoyment of the process, and help you to design and weave anything you can imagine.
