To sign the double letter "oo", start by forming the ASL letter "O" with your dominant hand. Bring all your fingertips to touch the tip of your thumb, creating a round "O" shape, with your palm facing forward. To indicate that there are two "O"s, hold this handshape and slide your hand slightly outward to the side (to the right if you are right-handed).
When fingerspelling the word "moon" (M-O-O-N), you will use this sliding "O" motion for the double letters in the middle before finishing with the letter "N".
To fingerspell "book" (B-O-O-K), start by signing "B", then transition into the "O" handshape, slide it slightly to the side for the second "O", and end with a "K".
For the word "food" (F-O-O-D), transition smoothly from the "F" handshape into the "O", slide it outward for the double letter, and finish by forming a "D".

No, you do not need to form the letter twice from scratch. Simply hold the "O" handshape and slide or bounce your hand slightly to the side to indicate the double letter.
You should slide your hand slightly outward, away from the center of your body. If you are right-handed, you will slide your hand to the right. If you are left-handed, you will slide it to the left.
The movement should be very small—just an inch or two. Keeping the movement compact helps you maintain a steady rhythm and stay within your comfortable fingerspelling space.
