I have only been playing a few months and I have noticed that as the temperature is dropping (I am in Sydney, Winter is approaching) it is a bit harder to get the rosin on the bow. Now Sydney does not really get that cold, but I am finding myself breathing on the rosin before I apply it so it will transfer. (I use Nyman rosin by the way). Is this normal? I know that it will be harder as it gets cooler, but since the winters are fairly mild and people obviously play bass in much colder climates, then it should still apply well. Any advice from those more experienced?
