RE: Project ghouls
I love unit fillers, so here are some Ghoul unit fillers ideas:
1) Ghouls eating. Simple, but effective! Bloody human parts everywhere (legs, arms, guts etc). You can use a 40mm base and have 2 ghouls(even 1, or more than 2 if you want) feasting or fighting for the "delicacies".
2) Ghouls coming out of a crypt and/or maybe around it (That's my favorite!). As mentioned earlier Garden of Morr terrain pieces are very good unit fillers. Also, i've bought some great Crypt minis from Armorcast. You can paint something like, a crack in the crypt's wall and cut a ghoul in half, make it look like it's coming out of the wall. You can cheat a bit at this part. Just find a photo of a crack in a wall and print it, make sure it is the right size. Glue it on the wall and paint it.
3) Ghouls coming out of holes in the ground. A bit tricky, as you need to give some height to your bases, or do some heavy basing work! Some cork here and there to create the illusion of depth.
4) If you have the frightened, running citizen from the Giant plastic kit, you can use him to create a mini diorama. Ghouls chasing him.
5) A Witchunter fighting his way through hordes of ghouls!
