Thanks 
kate, I made it all myself. I got this picture, put it on word and added the text on top. Also, when you google 'santa stamp' you'll get a few so I printed that with our address on an envelope. Last year I used this background. Really easy to do and I was able to truly personalise the letter to DS.
pigley, looking forward to your blog this year, will be reading 
MrsDimples, throughout the day the elf just moves to random places in the house. He doesn't do anything special as he does over night, but he just plays a bit of hide and seek. Well, that's the rule we made up as we had the same dilemma. Obviously he only moves when the child isn't watching as he can't be seen using his magic 
At the moment, Jingle is still in his spot from last night, but when I take DS upstairs later to get him dressed I'll just quickly move him to another spot. And then again when he naps etc.. At least it means you can break up the 'night scene'.
