Spoof,

I have a Thompson whip finisher.

I'm right handed but I wrap my thread 'backwards' to what every book/manual recommends or shows. Always have.

I just use the whip finisher in the same direction I'm wrapping the thread. Works fine.

Don't get too caught up in the directions. The whip finish is just wrapping thread over itself to lock it in place. Every tool I've ever used for this will do it in either direction.
