So, I had a thick (5cm) lump of insulation foam, but it wasn’t really enough to do anything suitably useful, maybe a stand alone hill, but of course the Bronze Age-y-ness of the Oathmark undead meant a long barrow…
Of course, me being me and not wanting to have a sizeable bit of unplayable terrain, I wanted an interior…
Thankfully, for some reason, I had a hot wire cutter still in its packaging (the model shop in town closed about twenty years ago) and it was just wide enough so cutting out the interior wasn’t horrendous. Straight vertical edges were though. After a bit of fiddly trimming, the interior walls were lined with 5mm foam cut into slabs and textured with a rock. Larger stones (and the roof) were done with 20mm blue foam - I swear the black foam takes imprints from the rock better than the blue. The slab motif continued to the exterior. Much evening out was done with sandpaper and air dry clay (budget meant limiting myself to what I had available).
The bits cut out of the interior will eventually become smaller closed off barrows.
