depends on how long you want the hair. the longer = the more hanks
and it depends on how "full" you like the hair to be.
Assuming you only put hair in a plug once (I do more than once sometimes for a fuller look) and assuming a g1-hair length (cut the hank in half), maybe a dozen hanks?
I'd use lucky clover or unlucky clover
and sugarplum
