In the Deaf Community, you introduce yourself by fingerspelling your name. Fingerspelling is a skill that requires a lot of practice to become proficient.
When you fingerspell a word, work on the continuous flow of one letter to the next, rather than spelling the word letter by letter.
When you fingerspell a word, avoid "bouncing" or "stamping" the letters as you spell. Also, your arm position is to keep your elbow down and your arm relaxed.
When you read someone's fingerspelling is not easy. It takes time to develop skills. Everyone approaches fingerspelling differently. But all agree that it takes practice, practice, and more practice. Here are three suggestions:
Working on recognizing the shape and the movement of letters and letter combinations.
Working on catching on to the first and last letters of the word and using spelled.
Ask the person to spell the word again and again until you understand the word.
