I have a friend who is ambidextrous and has only recently started learning, she keeps switching hands until I insisted she pick NOW or forever confuse and aggravate people.
On a related question: what is the meaning of touching the wrist of the dominant hand while fingerspelling something? I had a teacher who did it several times and didn't get to ask why...
Holding onto the wrist keeps new signers from "bouncing" their finger spelling. Lots of new signers bob their hand as they strike each letter. Some people do it worse than others. I'd never suggest to always hold your wrist if you can do it without but for those who give each letter 1-2 feet of air? Oy. Haha
Was she doing it between words?Not holding it... touching the wrist just below the palm of the hand with the index finger of the non-dominant hand. This was the teacher doing this, remember...
