Does linen shrink in the wash?
linen will shrink A LOT!!! in the dryer, but i think it is fine getting wet and air drying
Do fabrics that came from living sources shrink more in the wash than fabrics not made from living sources?
Yes, cotton, wool, silk and linen do shrink. This is mostly because the way the fibers are made into thread involves twisting them, and in the wash, the twists get tighter, causing the fabric to shrink. Synthetic fabrics are made from continuous filaments, and therefore do not shrink. Some synthetic fabrics will wrinkle badly, causing the fabric to appear to shrink, because of the crinkling of the fabric.
