dunno if you can see this.
it is done on mdf craftwood - quite a small trial.
i used lime putty mixed with crushed marble sand,two coats.
i used oxide pigments and lime water.

i wonder if fresco is my ultimate fate.

i would be working in this freeform abstract way - it is
where i express myself easily by default since i don't
have graphic skills. so i play with color and texture.
