Threaded in patterns
Threaded-in patterns are tablet weaving patterns that require no changes in turning direction or twisting. The entire pattern stems from the initial threading direction and colours of the tablets' threads.
All the cards are continually turned in a single direction for the entire length of the band, which makes for a very quick weave.
This generally makes for a fairly simple, repeating pattern of a length that equals the number of holes in the cards (usually 4 so most patterns have a 4-row repeat).
There has (in the past) been some controversy over whether threaded-in patterns are period, but apparrently some examples have been found - if there is a link to these it would be appreciated.
