Here’s a quick tutorial for making a very simple yet effective crater for blast markers or just for varied terrain.

Materials Needed:

  • Pink foam (1/2″)
  • Hot wire foam cutter
  • Whiteglue
  • Sand
  • Base material (See below in step 3)

Procedure :

Step 1: Mark the foam

Mark the outside circumferance of your crater in any shape you want (a simple method is to take a roll of tape and draw a circle using the outside circumferance).  Freehand the inner circumferance approximately a half an inch from the outer.

Once you have both circumferances drawn you want to freehand another line between the two to rougly mark where the topmost portion of your crater will be.

Step 2: Cut the foam

Just cut the outer circle at the line and then carved the inner circle with a knife or hot wire foam cutter.  If using a wire cutter, poke a hole in the middle of the circle and run the wire through the whole and reconnected it so that you don’t have to carve through the sides of the crater.  You will now have a donut shaped piece of foam.

Step 3: Make a base for your crater

You can use just about any material for this that you want.   My personal preference is a piece of MDF, but you could  just as easily use a coffee lid, cardboard or plasticard for the base.  Draw around the craters outer edge and cut it out to shape. Once the base is cut,  paint both sides a base color of brown.

Step 4: Attach foam to base and add dirt/sand

Glue the pink foam to the base (white glue, wood glue or hot glue work well) and add a few coats of brown paint just to create a base for the dirt.

After giving the whole thing a decent coat of brown, make a 50/50 glue/water mix and cover the whole thing and add sand. 

Make a few piles in the the crater for variety but for the most part  just make a light pile of sand over the entire crater.

To get the sand to stick keep gently adding the glue/water mix several times over the next couple of days allowing it to dry completely between applications.

Step 5: Paint

Start with a wash of black (50/50 black and water) to get shadows.  Then a drybrush of brown and another drybrush of tan.
