My sunglasses had got totally squashed and bent out of shape in my school bag but I hate throwing things away so I popped out the lenses and cut out some photos to fit and superglued round the edges of the frames and just popped the photos in. It is easier to pop out the bit of the sunglasses that rests on your nose or cut it off but this isn't necessary. Also goes without saying be careful with the super glue- sounds obvious but I got it everywhere!
