You want something rigid. If you use something floppy, you'll have to seal all around it and hold it in place while it dries. Eggcrate light diffuser is often used for big cichlids, but platies would swim right through.
That is a absolutely great idea. I might have to talk to my boyfriend about doing something like that. I wanted to get a divider anyways, and this seams like it would work wonderfully, other then my tank already being cycled, and fish living in it already... Grrr...

That sucks, Can try Michael's, Handcock Fabrics, or any other fabric store... If it does not work, I do not see why a mesh type screen wont work for this, just be sure to soak it in cold water and bleach, before you make it, and also make sure you wash it off completely after the bleach too.
