now that it is Layout Building time

On my last layout I had the roof replaced. All kinds of shingle dust and bids would fall on my layout. I used very thin and light painters drop plastic. It's so light it didn't even hurt the trees and telephone poles. Worked very well. Don 

this tarp that i have is extremely light,  15X20 and it might weigh a pound, the material for a dust cover is really not the issue, probably many different things that would work

the real problem is for the sake of a better word is a delivery system, a way to put it to work, a way to deploy it quickly and effectively but not damage any of the  delicate work that has been created,  all of my buildings have antenna, water towers, some have miller engineering bill boards (they are way cool) I now have three of them including the barber pole  so the object of this discussion is how to actually use the dust cover...  i know some places where one can get old parachutes, but the cheap plastic tarps that are probably something like nylon or even spinnaker material from the sailing world, it is light  not cheap but light

my little layout that i am replacing is quite easy to cover up but i just ran out of space to do anything, i mean it is crammed full of 'stuff'
