Here are some goggles that I made to protect your eyes while playing quidditch, fighting Voldemort, and cutting onions. And all the materials were basically free!
Here's where I got everything:
-The leather on the front came from a baseball. (I found no use for it since I never play baseball)
-I used some gatorade lids for the eyepieces
-And black rubber around the eyepiece is from a bicycle inner tube
-The white leather was a scrap that I found in the bottom of my fabric drawer. 

-And I found most of the other things in a junk yard
Voldemort will no longer defeat us with a sharp stick in the eye!!
Here are some earrings...
These were really easy to make. It was easier than going to a store and buying some. I just found some old buttons and glued earring backs on them. 
These are some earrings that I made from old buttons. My grandma has three giant buckets of buttons at her house. My sister and I looked through them and found some cool ones to make earrings out of. I took the back off these buttons by using wire cutters, then I sanded down the little stub that was left. I got some earring posts and super glued them to the buttons. The earring backs can be found at nearly any craft store.
