How to create a paper mailbox for your door

Get a piece of paper any color of your choice

Fold paper in half long ways

Crease paper where it needs creased

Fold one side and crease

Tape the fold so nothing will fall out

And then do the same on the other side

This is what it should look like

Flip the paper over

And write mailbox on it or whatever you want

Make sure you write PAPER ONLY on it because it can't hold heavy objects

Last but not least decorate it and tape it on your bedroom door or wherever you want
