Templates to make 3D glasses the easy way

Hi Everyone.Been looking around and came accross these two websites, where you can printout your own templates for making 3D glasses.But what it does not tell you, is that you may need 2 layers of red/blue, depending on the shade of cellopane you buy. If it is to light in colour they will not work, so if it's not dark enough then use two layers, which is what I use.So just print out ethier of these templates, and start making your 3D glasses.http://www.exploratorium.edu/history/PPIE-3D/template.htmlhttp://www.idido.com/3dplans.htmlfeel free to use what template you like and happy viewing in 3D.Just thought I would post these for anyone to try for themselves
