Tyndall Stone Wall

I am making a Tyndall Stone wall.

I have prepared my palette, just as Julia Caprara says to do. Torn strips of fabric...

..lengths of thick yarns, tapes, ribbons & threads are ready for building up in layers on the burlap base. I have 3 stone blocks under way. I'm not sure how many I will need to make a wall.
I'm now thinking the title should be something like 'Walls Talk'.
