What can I make with square stick-on mirrors?

Please send us a pic and dimensions.

is this a dresser mirror still mounted on its “legs”?

With a frame, you could make trays, just add handles to the frame and Mount the mirrors to some thin wood as its backing inside the frame. With decorative frames you could keep them on your dresser to hold perfume bottles or whatever. With a long frame the width of the mirror tiles you could use on a dining table and put your table scape on it. You could also use them as mirrors on the walls.

You could frost them and hang them on a wall, thanks to Pinterest!

Size? 12" or 1", size matters!

I would safely break them into smaller pieces and use them as mosaic tiles for many mosaic craft projects where you want high shine. One idea would be to cover a round object and make a garden gazing ball.
