alright, well I'm at the point where I need a piece of Ravel, unfortunately I sold all my handkerchiefs and killed the person that I sold them to. I've been looking all over the place for another one, but to no avail. Any suggestions?

You should be able to find one in the Brothel unless you've sold those ones too.... the only other thing I can recommend is to hack the character and add in a handkerchief.

There's a spare handkerchief in Finam's home.
