I'll make sure to not hold it in my crotch LOL
Where can I get these bases though?
An easy way to dress up bases is to do the sand and glue/water trick I describe above, paint on some patches of grass, and then run a fat black Sharpie around the sides of the base. If you keep an old paint brush to apply the glue/water mix, then dip the base into a little container with the sand, shaking off the excess, let it dry, paint the grass on, then run the marker around it, the whole process takes moments to do (with the drying in between taking a bit, if you even want to wait for it to dry). It's a cheap and quick way to do army bases or lots of conversions without much time or money investment, and they look just fine on the game table.
DM Scotty also has an easy, cheap way to do flocking, and all it requires is a pencil sacrificing itself for the cause.
But that sand trick sounds fantastic and not too obtrusive. I am going to try that on a few of my minis.
DM Scotty rules!
And if you have a few bucks to spend up front, check in a contruction supply store for a bag of "fine" sand blasting sand (make sure it isn't the kind with other types of particles). You can get a 20 pound bag for less than ten bucks in some places and it will last you a lifetime. Last time I got one it had a tear in the top and had lost a bit of sand so they even discounted it more for me.
