Every year I make these. These are 'Shanot Tovot' or Jewish New Year cards. At the beginning of the Jewish New Year we greet each other with 'may you have a sweet new year','may you be healthy and happy', 'may this year be successful' and 'may you be inscribed (by G-D) for good, long life'.
Now days, when most of us find things on the net and send them out with a click of a button, from our comfy homey computer stations, there's a special added value to personalizing your message, hand writing it and sending it the old way, through 'snail mail'.
I love Rosh Hasana and love hand made gifts. They enclose in them some of the giving spirit used to make them, the invested giver's good mood.
Have a great new year, use it for good deeds:)
