Yeti? Big Foot? Wookie? Summer Yetti? Sasquatch? 

Yetis are white, they are cold weather creatures
that are able to hide in the snow & stay warm in the cold
with thick heavy white (or grey) fur.

These fella's are made in terracotta a deep red clay
so I'd have to cover that up to make them white
and I'm a believer in material integrity
so unless its an interesting effect,
adding a depth to the white with hints of terracotta showing through
I think I'll need to accept they aren't yetis after all
and go dark with their fur: leveraging the depth of the red
not hiding it.

lets see how the test tiles turn out
& we'll go from there.
