How do you feather?

I was doing hand work on a few pieces for my upcoming gallery show.  (See my last post for further info)....  and I realized I can really tell the difference on whether or not I made my feathers from left to right, right to left, top to bottom or bottom to top!  I wasn't really shocked as I know that I was only comfortable doing them right handed bottom to top for a long time.

Which made me wonder...  are you a righty, lefty or do you feather ambidextrously?

Can you tell how I did these?
