Here are the other three:
1. Hear the megillah reading
2. Give tzedakah (charity)
3. Give shalach manot (food gifts)
Of course I could just call friends and invite them over but these invitations, shaped and folded like a Hamantaschen cookie are too cute to not send out!
After cutting out the circle, fold it to form a triangle, just like you would fold Hamantashen cookie dough.
Print your invite on colored paper, cut into a triangle and glue into the center.
