different artists work at different speeds and they also work using their own prefared needle configs, some would use small mags and others would use rounds, I would probably use rounds for that pice but slightly spread the needles out a little bit.

i would say about 3 and a half hours work

Impossible to say, can’t really make a decision online what I’d use, depends on alot. At a guess something like a 5/4 stack and a 3 or 5 round.
