/cgl/ - Cosplay & EGL

I'm going as Zoidberg to a con next month, and while the mask I bought looks great, I can't see out of it.
So far, the solution I've come up with has been to cut out the white of the eyes and try to replace them with these googly eyes I found and use some plastic with holes to see through. However I'm not sure what the best way to attach them is.
Or maybe there is a better way to do this whole thing?
