draw, sketch, paint
繢 centers on creating visual art by hand: drawing, sketching, or painting. The meanings all involve producing an image on a surface.
繢 combines 糸 (thread) with 貴, which likely contributes the sound. The exact historical development is uncertain, but the character is associated with drawing or painting, possibly through the idea of using thread-like lines.
The left side 糸 suggests fine threads or lines, and the right side 貴 looks like a precious object. Imagine using delicate silk threads to draw a valuable painting.
For カイ, picture a kite (カイト) whose tail is made of painted silk threads: kite -> カイ, and the silk 糸 is used to draw the kite's design.
