It's been way too long since I've had a proper session of tablet weaving, trying some more to figure out a good method of weaving twilled pattens without a written pattern... but somehow, there's always too little time. (Saying "yes" to too many requests, trying to organise some more workshops, going to fairs plus having to keep up and to cope with all the current bureaucratic bullshit the EU tends to throw at people does not help either.)
There's some links for you at least, though, related to tablet weaving:

Lise Raeder Knudsen has a pdf book about Gotlandish Tablet Weaves on her website, free to download. It's in Swedish, with a very short English summary, but might still be interesting to you for the (slightly grainy, black-and-white) pictures of the originals. You might also want to check out her other publications in the list, which are partly available to download.

Tablet weaving, being slightly different from "normal" weaving, is a fascinating thing all around, and I always find it interesting how differently people approach the topic, and from how many different aspects it proves to be... complicated. Case in point: the attempt to write a tabletweaving simulation, published on the Penelope blog. If you are intrigued by how tablet weaving works, check out Sarah Goslee's explanation on the String Pages, she does a wonderful job at explaining the nitty gritty inner workings. (She also has an article about this, with pictures, in Ancient Textiles, Modern Science.)
