Artists often refer to "negative space" in artworks; that is areas of nothing.  Graphic artists refer to "white space" for printed items where nothing is printed.  The purpose of negative space / white space is to set off areas where there is "something".  Too much "something" can create a type of visual chaos that is not pleasing.

I know the stuff made for NKP flies off the shelves. I'm just wondering where all the NKP modelers are on these forums and facebook. I realize the NKP merged into the Norfolk & Western in 1964, but it just seems there are not very many NKP fans online. I sure would like to share my love for the Nickel Plate with fellow modelers, but it seems they are few and far between. I turned 13 years old 2 days after the merger, but it was the line I grew up with. My dad was a NKP fan, and my grandfather was a NKP Cop.

I am re-posting this as the link was broken sorry about that. My son build a foam cutter that we use to build a hatch over the staging yard ladder using pink foam and plaster cloth. I do not dip the cloth as that is messy. I work with the cloth dry and use water and a paintbrush. I buy the cloth in bulk of 64 rolls and it works out to less the $2.00 per roll 4 inch wide by 180 inches ( http://www.amazon.com/Creative-Mark-Plaster-Cloth-Large/dp/B0049V1BY0 )

hope this is helpfuly to you
