Find an old makeup mirror or one of those mirrors you keep in your purse. What I did was I carefully popped off the little circular mirror inside one of my old makeup bronzer holders from mac cosmetics.
Here's the mirror I removed.
Search on google images for a sun to resemble this one. You want the cool looking rays to show, and it doesn't matter what the middle looks like; it will be covered up anyways. ;) When you find the right one, print it out.
Make sure the mirror fits perfectly in the middle of the sun. You may have to resize and print your picture a couple of times. D:
To make sure the rays of the sun aren't flimsy, mount the piece of paper on some cardboard. I used a piece of a cereal box :P Then, start cutting the sun out. Also, you may need to already glue the sun onto the cardboard so it doesn't move around when cutting it.
This is what it should look like after cutting it out :D
Now you need to use a hot glue gun. Turn your mirror over and glue the back using your hot glue gun. Make sure it's hot! After immediately putting the hot glue on the back side of the mirror, mount the mirror in the middle of your cut out sun. Be careful, don't burn yourself though :O
After carefully gluing the mirror on, here is what it should look like.
Now you need to outline the mirror. I used a puffy 3D orange paint so the outer part of the mirror wouldn't cut me. D: You may need to purchase some 3D paint or what ever you would like to use, but I already had some.
Very carefully and slowly, outline your mirror.
Now, you'll need to use some colorful glitter glue! :) You're gonna have to outline the rays of the sun, to make it more colorful and pretty. :D
You're gonna have to put your sun mirror on top of a piece of paper, to avoid getting glitter glue on your workspace. Here's what you should do. <--- :P Wait for that to dry when you're done before removing it from off the paper.
Finally, you're done! :D Now you have your sun mirror to carry around in your bag :D Or you can hang this on your wall by either adding a string or two sided sticky tape OR make it a magnet. :P
