i wish to know how to determine if enough rosin is applied onto the bow? pls help...
when you feel the bow is floating on the string and you need to dig into the string to make good sound, then you need to rosin your bow.
if you see rosin dusts collecting on the violin surface under the strings, or fingerboard, it's a little too much but still ok. but if you bow and you see "smokes" coming out from the bow hair, it's way too much...
PS: to answer your PM, sorry i really don't know when i'm ok.

How tight should the bow hair be? How do we know if it is tight enough?
usually, the distance between bowhair/stick at the middle is about the same width of the bow stick.
i the bow bounce too much on normal bowing, tighten it more. as a general rule of thumb, never tighten to the extent that the bow stick looks straight, it should leave at least some inward curve on it.
