Gray Code Pattern

The chart below shows how each tablet should be threaded. The four rows of colors are for the A, B, C and D holes respectively. The threading direction indicated by the diagonal line in the 5th row. When looking from the cloth beam towards the warp beam with the tablets facing to one's right, the direction of the diagonal line shows how each thread should pass through the tablet.

This nextchart shows how each row shoulf be woven. The first column is the row number. This is followed by a separate column for each tablet. For a given tablet, 🡑 indicates that the tablet should be rotated forward, and 🡓 indicates that the tablet should be rotated backward. The number after the arrow says which edge of the tablet should be on top after the rotation. This can be used to verify that all tablets are in the right place before throwing the weft. The last three rows show the final, minimum and maximum accumulated twist for each tablet.

Below is a rendering of what we anticipate the resulting weave might look like. Note that, for proper rendering, row 1 of the pattern is at the bottom of each of these images.
