Tea towels:
material, yarn and weave.

Good and lasting tea towels are made of a fabric of at least half-linen quality (i.e. with a weight proportion of at least 40% linen), using single-thread or twisted yarn. If yarn is used in the weft and a firmer twist in the warp, a more hard-wearing, long-lasting half-twist fabric is produced.
The type of weave affects the towel's quality too. Depending on intended use, you can choose between a finer plain weave or a more sturdy twill weave.
