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
