The thinnest hair-like material I've seen is Craft Fur. You can spin it in a dubbing loop, then palmer that. Dale "iaflyfisher" had recently shown me some of Gary Borger's patterns that he ties with this technique.
Here's a link to one of his patterns:

I could be way off with this suggestion. Any chance you could post a picture of that pattern you are trying to copy? Maybe some of other folks here can give you better suggestions once they actually see the fly?
