One of the most important, yet often overlooked aspects of building you army is having a cohesive basing system for your army. All of my 40k Orks are based in the same way. I wanted to change it up a bit for my Ironjawz, so I decided on a dungeon floor, ruined structure look. I used a similar approach on some of my Deffskullz with a different color scheme.
To do this simple style base, you will need the following items:
A sheet of plasticard (I used an old sign)
Skavenblight Dinge (GW)
Warpfiend Grey (GW)
Underbelly Blue (P3)
Step 1: Cut your plasticard.
