I saw on pinterest that there was a pattern for sale to make a mouse in an altoids tin. The pattern looked really cute, but I can usually eyeball something and not need a pattern. So here is my version of a Mouse in a Tin.
Start with you altoids tin.
Cut felt to fit inside the top and bottom of the tin and glue it in place.
Make a cute mouse out of felt and fabric scraps.
Make a top blanket and glue it to the bottom of the tin so it won't fall out. Then make a small pillow out of a fabric scrap.
Inside of tin.
