Took an old frame I had in a drawer (really cheap dollar store type). I cut duct tape strips the length of the left and right sides (with about and extra 1/4") and adhered it to the outside.
I made sure it was covering the corner just slightly ( to insure a good looking corner joint...no gaps). I then wrapped it toward the inside.
In order to get it to go around the inside corner, I just trimmed each side at a 45 degree angle once it was at that point.
As you can see the right and left side didn't have to be perfect since the top and bottom pieces will cover it up.
I repeated the process for the top and bottom piece (I had to be more careful with my cut since you would see that edge of the tape. Turned out pretty cute and more importantly...my daughter loves it!
