thread
絲 centers on fine, twisted fibers used for sewing or weaving: a thread.
絲 is a doubling of 糸 (thread), reinforcing the idea of fine twisted fibers. The form visually represents multiple strands.
Two 糸 (thread) side by side: imagine twisting two thin strands together to make one strong thread.
For シ, picture a single silk thread shimmering: the 'shi' in shimmering cues シ, and the thread glistens.
