With a fresh blade for your modelling knife, cut out small rectangles of foam. The optimal size (when compared to a Mordor Orc) is 1/8" tall x 1/2" wide x 1/2" deep. Be very careful when using modelling knives, as they are very sharp.

Shave the foam rectangle into a roughly egg-shaped form with your knife. Watch your fingers.

Push floral wire through the foam. Allow approximately 1" to protrude from the "back" of the cocoon. This bit will act as an anchor during Step 7.

Wind floral wire around the cocoon to simulate thicker, stronger strands of webbing.

Cut the floral wire once the cocoon has been covered to your liking. Bend the end of the wire back upon itself and push it into the foam and hide it among the rest of the wire wrapping.

Straighten the 1" anchor wire on your assembled cocoon.

Push the cocoon's anchor wire into the foam cave walls. Try bunching a few cocoons for variety.

Finally, use more strands of floral wire to "strap" the cocoons to the tunnel walls.

First, with a 25mm round base and a pin vise in hand, drill two holes near the centre of the base approximately 1 cm away from one another. Cut a length of wire to about 6". Wrap this wire around a bottle of GW white glue or another object of similar girth. Bend the excess wire at right angles to the wire hoop. Cut off any extra wire (watch your eyes!). Insert the tabs into the holes in the base and dab a drop of superglue on each tab to secure them.

Once the superglue has dried, take a glue gun set to the lowest heat setting and apply a ring of hot glue to the wire. Now, run thin strands of glue back and forth across the width of the hoop. Apply glue to both sides of the wire. Your web markers can be as sparse (centre image) or as dense (right image) as you like.

Once the hot glue has dried (it won't take long at all), prime your webs with White Spray Primer. After the primer has dried, paint the base with Chaos Black paint.
