I bought the mirrors at my local craft store- Hobby Lobby. The large one is about 6 in (2 per pack). I bought a pack of the lg, med and sm ones (25 per pack) I also bought an assorted size one so I had 100 little mirror total. Some were chipped so I just threw those away. I used metallic silver spray paint. I already had the kabob stick and hot glue gun. It was super easy!
So this is what you need:
6 in mirror (or any size you like)
Kabob sticks (I had 2 different sizes, but you can cut yours if you want too) I had 32 total.
Little mirrors in assorted sizes- you can use and many as you want.
Hot glue and glue gun
Cardboard circle the same size as your big mirror (you will put this on the back)
Wire or some type of hook to hang it
First spray paint the sticks. Then after they are completely dry glue them to the back of the mirror. I put the longest sticks in the 12, 3, 6, and 9 position (like clock) then I was able to space them. I started measuring (drawing lines on the back of the mirror like a pizza), but I decided just to eye ball it. I marked the bottom of the sticks about a half of an inch so I knew how far to glue them. Next, I flipped it over and glued the mirrors on.
When I was done I went back and added a bit of glue to the backs of the small mirrors. You probably do not need to, I just wanted to make sure they stayed on well.
I used a small metal wire that we had in the garage to make the hook and glued it to the back. Then once that is all done you get to clean up all the little "cob webs" that the hot glue left behind :O)
