Narrative:

Climbing to assigned FL200, I entered clouds and almost immediately begin picking up moderate mixed icing. I was on vectors (heading 200) to intercept the SID. Upon ice penetration, I informed controller and advised I was turning to heading 090 degrees to descend to VFR. Breaking out at about 15500 ft, I canceled IFR and proceeded to destination VFR. ATC did not advise of any conflicts, and was extremely helpful.
