[Cob] Water colour- Rice Hull Ash

[goshawk]

Sorry not photos yet. Might start thinking about that soon
however, but basically I've done both. In one case, I took
wet lime plastered walls and "painted" the wet lime with
pigment. Very basic colurs  and it looks good. 

In the case of the watercolor it was a cured wall. A much
small painting too. I like the minWax, will give it a try. 

Great turkey day to you and everyone too!
