I don’t know how many stitches per minute cause I haven’t tried it but, I’m pretty slow. 800m takes me about 3 1/2 days. I made a virus shawl with that amount of yarn in that time.
Fantastic! Sounds like you are loving the dream
It depends how big the yarn is, the bigger the yarn/hook the faster it is for me. Smaller pieces take me way longer which is a bummer cause no one wants to pay a bunch on a tiny items that took forever. But a big item that took no time? Sure whatever price you want.
Some of those bulky yarns are stressful on the hands! So much drag
