Decorating a plain white envelope is a fun thing! Well, at least for me it is (^•^)
I started off with a plain white envelope, drew a little bird, added a large sticker, and stuck a patterned trim at the bottom. I also calligraphed the recipient's name in white ink. So far, my calligraphy is chicken scratch, but I really am trying. I will be good at it one day (^•^)...crossing my fingers.
