We also do it that day, so that our Elf on the Shelf, Buddy...has his special place to land when he flies in from the North Pole that evening - the top of our Christmas Tree...snuggled up by the warm light of the star.
I should note: Buddy underwent a quick...very mild surgery this year as well - he now is the proud owner of BENDABLE LIMBS!!
It was pretty easy really....just found a little how-to online, and I had all the supplies on hand. It took me probably 45 min to do all 4 limbs from start to finish. SO excited to be able to place him in funny positions/places and have him holding onto things himself, instead of TAPE everywhere!
Welcome back to your home away from home Buddy!
