Narrative:

Planned trip to occur during the afternoon. Initially planned as an IFR trip but before takeoff; elected to proceed VFR to remain below the cloud bases and possible icing conditions. Flight proceeded as planned but at just over the halfway point; lowering cloud conditions forced a cruise altitude of 1;000 feet AGL. Finding this to be uncomfortable; I contacted center to request an IFR clearance to my destination. Once granted; I climbed to 5;000 feet. I had previously reviewed icing charts which indicated that once past the halfway point; there would be no icing at 5;000 feet. Furthermore; a pilot on frequency (by this time; approach control); reported VMC; between layers and no icing. During descent for the RNAV approach; detected trace icing which became light rime as the approach progressed. Nearing the ground; the ice began to disappear as I encountered warmer temperatures. The airplane's handling was unaffected and the approach and landing were otherwise uneventful.with the clarity of hindsight; instead of requesting an IFR clearance and climbing; I would have initiated a 180 degree turn and returned to my departure airport or a suitable deviation airport. My airplane is not configured for icing conditions and no ice has to be my rule. Even though the winds aloft forecast indicated that I should have been below the freezing level; when it's close; sometimes it doesn't go your way. Won't do that again; not worth it.
