Just wanted to add, my sister when little wanted a letter from Santa, but was very..shrewd. (still is)
My mom wrote a letter on the computer, put it in calligraphy print then traced it. When she got the letter, sure enough she compared handwriting.
I thought it would be a cute idea for a kid who keeps it so later on won't realize mom wrote it/ it was printed.
I am so excited for December to get here now! Thanks for all of the ideas!
