A description of the "10-minute warp", a continuous warping method, is available from from Linda Hendrickson.
This tablet weaving theory page is a technical look at how exactly tablet weaving works, including S and Z threading and twists, threading the tablets in several colors, and the different structures possible, including twill and four-color floats (Snartemo). A simple Snartemo pattern goes with the theory page.
These are not nicely formatted yet, but here are my explanation of Snartemo patterns, a Snartemo pattern worked step by step (in MS Excel format), and my version of Hansen's Snartemo pattern from the original Norwegian band (also in Excel format).
Here are the preliminary results from my study of two-hole tablet weaving.
I've finally pulled together the results of a year and a half of work on tablet woven structures.
Nancy Spies has finally found a publisher for her book
Ecclesiastical Pomp and Aristocratic Circumstance: A Thousand Years of Brocaded
I am in awe of Nancy's brocaded bands (you can see some on the page referenced above, and more in the weaver's hand gallery) and she is a meticulous researcher - this book is fantastic.
There are several tablet weaving organizations and mailing lists.
