The Weaver’s Infinite Scroll
In a dusty workshop, a master weaver battles a rigid loom. The frame only holds a small square of fabric at a time. It is frustrating work. Whenever he finishes a section and rolls the scroll forward, the pattern he just wove disappears. He loses sight of what came before.
This creates a nasty flaw. Since he cannot see the old threads, he has to guess where the lines continue. The result is a visible join, a jagged break where the pattern does not quite line up. The design looks fragmented because he starts cold with every turn.
He tries a clever trick. Instead of rolling the finished section completely away, he keeps the bottom fringe of the old threads on the new frame. By keeping these 'history threads' visible, he can physically tie the new knots into the old ones. The pattern flows across the gap.
But a new headache appears. He usually counts stitches from the top of the frame, like 'row five'. Now that old and new sections overlap, the numbers get muddled. Two threads sit in the same slot, so he does not know which 'row five' the instructions mean.
To fix this, he stops counting from the frame's edge. Instead, he measures distance from his own hand: 'stitch three rows back from here.' By switching to relative distance, it does not matter where the fabric sits. The instructions work perfectly anywhere on the cloth.
With history threads and relative counting, the final roll is flawless. The tapestry is miles long with no breaks. Vines and shapes flow naturally from start to finish. It looks far better and finishes faster, because he never has to stop and recalculate at the joins.
