The Black Whorl Echo has even higher and lower ratios than the Golden Whorl Echo. We began printing our whorls (or pulleys) to create a more sustainably made product and rely less on imported hardware. Below is a copy of the Echo ratio guide.

Beginner tip: start at the middle pulley/whorl and move up (bigger whorl) to spin slower for bulkier yarns and move down (smaller whorl) to spin faster for finer yarns.
