black foam board light trap

[MMJcali]

I saw a thread on here not too long ago that had detailed instructions on how to make a DIY lightrap out of black foam core board...

not in link-o-rama (there is one diy tut but not the right one), searches came up blank...does anyone know what I'm talking about?

This is probably not the one you're referring to, but for the benefit of anyone else who finds this thread, take a look at Ichabod Crane's foamboard trap:

Easy to build and effective.
