Here's how we compose our letters to Santa:
I choose a couple of toy magazines/ads and tell the girls to pick out what they would like to see Santa bring them for Christmas.
We cut out the toy, glue it to a piece of paper, and then compile the pages into an envelope for Santa.
Every year when it comes time to fill out the envelope for Santa's address, I forget his address.
There's two ways to do this - make up an address and never really mail it (this is what I do and then I keep the envelopes in the girls' keepsake boxes for them to look at when they're older) or get the actual mailing address that allows Santa to write back to your child.
This year, I came across this post and it's something I'm saving for next year:
So, here’s how Operation Santa works: As per the program, letters to Pelznickel—addressed to the aforementioned 123 Elf Road address in the North Pole—that request clothes, shoes, toys, games, books, and other basic necessities will be fulfilled with the help of the U.S. Postal Service. It’s the Post Office’s amazing way of lifting kids’ Christmas spirits and giving back during the holidays.
I love that! I decided to use the above address on the lists we "mailed" to Santa, but next year I will have to remind myself to adopt a letter through Operation Santa.
