gauze, gossamer
紗 centers on thin, delicate woven fabric: gauze or gossamer, emphasizing lightness and transparency.
紗 combines 糸 (thread) with 少, which likely contributes the sound and possibly the idea of something fine or slight, reflecting the thinness of gauze.
The thread radical 糸 beside 少 (few, little) suggests fabric made with very little thread, resulting in a light, see-through gauze.
For サ, picture a delicate gauze fabric so thin it looks like a sigh: sigh -> サ, and the fabric is as light as a breath.
