To make your own crazy glasses all you need is my free printable crazy glasses template, which you can download here: picklebums_crazyglasses.
Then just print the two page pdf. You can either print straight onto some strong card, or print them on to regular paper and paste the pages onto some old cereal boxes or similar cardboard for support.
Choose your glasses and cut them out along with a set of arms. Measure how long the arms of the glasses need to be to comfortably fit your head and snip them off at the desired length. Fold the little tabs on the side of the glasses and tape the arms onto them.
Now all you need to do is decorate your crazy glasses and take your own crazy photos!
