The 3-way Montessori mirror (mirror box / mirror corner board) has been on my wishlist for some time now.
Yesterday when we were at the library I saw a small homemade version and I thought: I can do that.
What did I use:
3 square mirrors from IKEA
I didn’t have to go out of the house for supplies because we had mirrors and duck tape at home.
It was really easy. I started with the mirror that lays on the table. I turned it around and added duck tape to two sides. I flipped it over and attached one of the standing mirrors. I used a cup to prefend the mirror from falling backwards. I attached the second mirror and fastened the duck tape. Again I used another cup to prefend it from falling backwards. Then I taped to two standing mirrors together. Done!
Instead of duck tape, you can also use velcro. Which makes it easier to take it apart and store it.
