I can't help but reshare this infographic for Sukkot. Feel free to print out your own version and hang it up in the sukkah! I have one for ours, even though we won't be building one this year (Mr. T is indefinitely stuck in the UK, so Ash and I are relying on the kindness of strangers for meals, friendship, and sanity).
Also, if you're curious about the ushpizin and the traditions surrounding these special guests, check out my article over on About.com: The Seven Guests Who Make the Sukkah Special
Do you do anything special for Sukkot? Do you have any unique traditions? Let me know!
