Craftgrrls:

I am trying to do a craft with revamping these sunglasses, but i am having trouble with popping the lenses out. They are plastic frames. I tried to pop them out like normal, but I'm afraid that I'm going to break them.

Does anyone have any suggestions besides going to a lenscraftster to get the lenses out?

Lenscraftster is my last resort.

Thanks! :)
