I was putting together thank you notes for Tater's birthday. I wanted him to contribute in some way to express appreciation to his friends for coming to his party. I had him make some crayon and marker drawings telling him this was his thank-you note to his friends. I then cut out rectangles of his drawings and mounted them on card stock stationary. I used spray fixative, but you could use double-sided tape or rubber cement. I bought a pack of blank white stationery at the craft store for $5.
