1. Happy: The sign for "happy" is made by bringing your dominant hand to your cheek, palm facing inward, and then moving it outward in a circular motion.
2. Holidays: The sign for "holidays" is made by signing "holiday" twice. The sign for "holiday" is made by making a fist with your dominant hand and tapping your open palm twice.
Therefore, you would sign "Happy Holidays" by signing "happy" followed by "holiday" twice.
Here are some additional tips:
* You can add facial expressions and body language to emphasize the sentiment of the greeting.
* You can also use the sign for "season's greetings" instead of "happy holidays". This sign is made by signing "season" followed by the sign for "greetings", which is made by extending your open hand outward and then bringing it back towards your chest with a slight bow.
* If you are unsure about the proper way to sign something, it is always best to ask someone who is fluent in ASL for clarification.
