How to identify the wing side of full feathers?

[snowplow]

I have seen the diagrams showing how you can see what side the 'lip' is on a fully processed feather fletching.

How does this translate to a full feather. How do you tell if a random feather is right or left wing?

Hold the feather with the outside end (the end that doesn't stick in the bird) pointed toward you, edge up.  The quill will form a ledge on one side or the other of the feather. If the ledge is on the right side, it is a left wing feather, and vice versa.

Oh wow that's easy. Thanks you guys. I didn't realize the feathers grow favoring one side of the quill or the other. I thought the ledge was more or less manufactured when grinding or something.

Thanks!!

Just got a feather burner and my friends bringing me a bunch of turkey feathers tonight!
