Have covered the cavern corridors in rough builders sand in middle and small pebbles on outer edge. They have to dry now then I will be ready to undercoat black, then top coat brown and cream.
There are 6 already painted and ready to go, plus this lot gives me 19 corridor sections. One of the hardest things is having to wait for stuff to dry! And keeping the cats off what are basically a series of miniature litter trays!
