Hey Brad, the back of this swatch says:
TURFevolutions
Style/Color: Luxury/Spring Green
Order SKU: 910-664(6')/877-965(12')
One of the two Home Depots near me had it in stock; cut from a 6' roll it was ~$10.20 per linear foot (1'x6' section), so that works out to be ~$1.70 per sq ft. They did have some TrafficMaster brand 12' commercial outdoor turf that was very similar to this and cheaper @ ~$1.29 sq ft, but it was special order like Joe mentioned (it wasn't the 'Greenspace' I mentioned previously, as those were tiles vs off a roll).
From the side the pile on this probably 3/16"-1/4", so if I tried to set a Railking figure 'down in' it, the grass would be close to his knees, but the blades are very thin, yet densely packed so I think track and models will mostly sit on top of it. Another big plus, scratching and rubbing on the sample, it doesn't seem to want to shed at all.
BTW that's a real nicely finished layout Joe, very cool! This turf might be slightly darker, but I'm not sure cause the colors never look the same in pictures as in person.
Thanks for the tip Russell! I'll probably have a couple diorama type scenes that may have their own landscaping. I just want a large single piece of roll up carpet to use for now to give an easily setup impression of landscape even without structures (or with very few) on the layout. This stuff can be used on top of my modest 4'x8' layout table (that's only covered with the faux diamond plate rubber pads pictured above), or setup as a carpet central, on the fly.
Thanks guys,
Robert
