the person im making it for is like 5'11
Are you making it for someone? You don't want it to be to short and then the persons toes wont be covered :p and it depends on what pattern or stick you use.
so i have to do at least 20 rows a day to get this done in time, thank yu
-to be able to cover a person of 5'11, without covering his head.
first you have to decide what size you want
i wouls say five hundred across
