I work in a very corporate environment with dudes in suits and such.. and just can't openly walk around with an army book without feeling out of place, so recently, I decided to cover some books. You all may have forgotten this technique since you are long out of grade school, but I have kids that need books covered all the time.
Been working on the new arachnarok.. adding some pins to legs and using the heat gun to reposition. The result is a much larger and more aggresive feel.

Everyone seems to know you can sculpt greenstuff with an exacto or some dentist picks with a little water so they don't stick. Who doesn't have something like these: http://www.aboutsculpture.com/Sculpture-Tools.html
