Also, to make a version for small children or people who love to read (bookworms), take a pair of 3d glasses (hard plastic kind).
Step 1: Cut out lenses carefully and safely, if you have children around make sure to do it for them.
Step 2 (optional): Take sand paper and slowly rub away the remainder of the plastic lenses.
Step 3: Pick a glue, I haven't tried hot glue with my googly eyes so if you do, test it out first in case it melts them.
Step 4: Create a pattern for the eyes, heck, try different sized googly eyes for a funnier effect!
Step 5: Hand them to the reader as a gift or keep them for yourselves!
Sorry I didn't have a step by step, for these are ordinary sunglasses with edging around them and I did it on the fly. I'll edit this instructable when I recieve 3d glasses so I can show you viewers the steps much more easily.
