Well, the technique I used was a little something I call – “Hope Something Works”.
1. First I just tried fabric dye. I mixed up the dye and hot water in a 5 gallon plastic tub, using twice the recommended amount. I stirred the cloth around for about 30 minutes, then left it to soak in the dye overnight. In the morning I laid the cloth out to dry on the grass in my back yard. This ended up giving me a sickly dead grass green, not unlike my own grass, but not the color I was really going for. I used this mat for probably 20 or more games but was never really happy with how it looked. So eventually I had another go…
2. I sprayed the cloth using fabric spray (shown below). I used the brown and tan quite sparingly, just to add a little subtle color variance. The green was applied a little heavier but still going for more of an over-lay, rather than trying to completely cover the fabric. As it was, I barely had enough to do the cloth. I wish I’d have picked up another can of the green, but such is the price of being a penny-pincher. I left this over-night to dry and it made a significant improvement. Not the sort to leave well enough alone, I moved on to my next idea…
3. Using precise measurements of “what-looks-about-right” I mixed a concoction of water, india ink, and fabric dye in a plastic spray bottle. Stretching the cloth out flat on the floor, I sprayed it down with the green mixture and then let it air out for several days.
Considering I had no idea what I was doing, I feel pretty lucky with how it all turned out. And during play, the pile is low and soft enough that figures almost never tilt at odd angles. So far we have only used this cloth in three games, but I am confident the color will hold for quite awhile. Here is a pic of the products I used --
