I prepared a letter and an envelope for my Mah Mah yesterday. I decorated the envelope and was ready to drop it off the letter box. Unfortunately, Mami said that I could not use this envelope. I needed to insert it into another "proper" envelope, write the address and paste a stamp before posting it out.
What's wrong with my envelope? I already drew the stamp for posting it. Can you see the little bird with the word "Malaysia"? Isn't that sufficient?
This is the front of the envelope with my beautiful stamp
