Greenscreen with no enough green (Mirror)

[Ogi5EEB]

Hi Guys,

I have a very nice mirror in a picture frame and I want to use green screen in a video. I don't have a green blanket or anything so I would have to use a printer but it would be very time consuming to glue so much together because the mirror is very big. My question is it is possible to mark only the mirror on the sides?

Can you tape bright green construction paper to the surface of the mirror? You can always create a mask.

You would have to watch a few videos about masks and mattes to get 100% correct.
