I have a wish that cannot be fulfilled: I would like to meet the person who invented tablet weaving. As the oldest known tablet woven bands date back to neolithic times, meeting the genius who came up with the technique is clearly not possible. When weaving on a loom, the warp threads are raised or lowered by moving a sort of a comb to which they are attached (it is too late at night to go and look up the proper terminology, sorry). The brilliance of tablet weaving is that the lowering and raising of the threads is accomplished by turning the tablets that carry the warp.
I have created a Squidoo lens on tablet weaving. It contains the basic instructions and links to other useful sites. Here is a photo of a band I wove about two years ago:
