narrow, fold, furl, shrug, pucker, shut, close
窄 centers on making something narrower or more closed: physically narrowing an opening, folding or furling something to reduce its width, or puckering and shutting tightly. The shrug sense is a natural extension of drawing inward.
窄 combines 穴 (hole, cavity) with 乍, which likely contributes the sound and the idea of something being narrow or constricted. The exact historical development of 乍 in this context is uncertain.
The top 穴 is a hole or cavity, and the bottom 乍 looks like a person squeezing through. Imagine someone trying to fit through a narrow hole, having to fold their body and pucker up to get through.
For サク, imagine a narrow sack being pulled tight: sack -> サク, and the sack narrows as it closes.
