Found a tennis ball. Cut it in half with scalpel, cut out doorway. Cobbed it up
with PVA & coated the existing teasel with static grass & fronds of lichen I
harvested in the Gower when I was 10 (Looks very like scrub/brush. I'm back in
the Gower for the first time since then in a fortnight!) Stuck each one on a
seperate upside-down coaster (see previous posts) coated in PVA with added sand,
grit & extra Welsh lichen brush. Sprayed brown, not too heavy, Its OK if a bit
of green teasel shows through (vestigial greenery in the brush)

Captures the whole 'giant compost heap effect' one sees in photos

The whole 2 models out of one ball thing is neat.
