Ok, I've heard of that but I'm looking for specifics.  I dont want to walk into Home Depot and say "I need some plywood" and look like an idiot when they ask me, what size and thickness  

I've also heard about guys using Plexiglass on top of the seamless paper? Where do you guys get this stuff?

Get 2, 4'x8'x3/4" sheets of "CD" plywood.  They make "AC" but it cost more.

an underlay of plywood?

I second this option


Unless you want to rip out the carpet

Help!!!!  Currently I'm using muslins and am thinking about going to seamless paper.  Unfortunately my studio is carpeted, anyone else in  this situation and using seamless and if so what is your setup?

I've used a ton of 56" wide seamless in hotel shoots around the country, and almost always on carpet. (See MM# 121575 for most of my seamless-in-small-rooms work) The longer rolls are just far too hard to maneuver in and out of elevators, hotel rooms, etc and draw a lot more attention. 

For creating a hard surface under the paper, I use 2' x 4' pieces of masonite (called hardboard in someplaces, is brown, and very smooth), only 1/4" thick, taped together with gaffer's tape, and taped to the carpet in a couple places to prevent shift. Works quite well.

They come pre-cut to those dimensions at either Home Depot or Lowes and are much more portable, if you need to move them around much. For my particular use, plywood underneath would be overkill, more expensive, and less portable.

If you are using the long rolls of seamless, the same hardboard could be used in 4' x 8' sheets, if you need to take it up afterwards. If you plan on making an underlayment you can leave for awhile, I'd suggest a heavier substrate.
