What is the least expensive way to put up wall mirrors for my home dance studio?
Answers:
Lowe's and Home Depot both sell Mirror mastic in their caulking aisles. They cost about $3 to $5. Only other thing you will need is a Caulking gun which you can get for under $5. Two or three tubes should be enough for you to "hang" your mirrors. The cost of the mirrors themselves I don't know but If you wanted smaller sizes I know Lowes carries some mirror in their hardware department.

Have you looked at price of mirror tiles?

for a finished look... get the mirror you need (find a local glass shop for the cheapest price) the go to home depot and get wood molding that you can install to hold the mirror in place like a giant frame
i would recommend using a j-chanel for top and bottom of mirror so you don't have to glue it to your wall, the add the wood "frame"
