What do you do with your kid's letter to Santa?

Did you know that the history of letters to Santa Claus can be traced back to the 1200s, when children would write letters to the real St. Nicholas?{thanks wikipedia}

Here's today's community question:

What do you do with your kid's letter(s) to Santa? 

I decided a couple years ago, when my children started writing their own letters, that I wanted keep them.  They're pretty much priceless, don't ya think?  Really they hold as much importance for me, as does a lost tooth.  I guess some how they represent my kid's innocence.  I decided the best place to store these artifacts would be in the frame of their annual picture with Santa.

Here's Sapphire's letter.  Actually, this is draft # 6.  She's revised and recopied her letter at least 6 times already this year and it's not even December.  I stashed one of the copies and she'll mail her final copy to Santa.  

Dear Santu,

My poor spell checker is quite frustrated with me for not fixing Sapphire's spelling mistakes. Her whole list has red zig zag lines beneath it but I'm going to ignore it because I love how she wrote it.   

So what do you do with the letters?  Send them in the mail, file them in the recycling bin, stash them with the decorations, soak up the spilled cereal milk, line the kitty litter box?
