Here I am beginning to work on the office entrance.I am working mostly with pastels to add some color and weathering here and there.The field grass is from an old brush that my dog (Dolly) a Siberian Huskey/wolf, had taken outside a year or two ago and hid amoung her treasures in the backyard.I took a hammer and chisel and hacked it apart and now it is one of my diorama treasures.It looks just like field grass would look, in November, here in Canada.It has a nice rusty bottom were the metal pins are holding the bristles to the wood which gives it a natural earth color..I am using it as is, with no further coloration.I stuck the clumps in the microwave for a couple of minutes (while my wife was out)to kill any critters that may be lurking inside.I don't plan to use a lot of this stuff only for interest here and there.
