[Cob] Sand

[Kim West]

Do you make cob with this barefoot? If I remember correctly, the first sand
that we got, the one that cut our feet, was called "concrete" sand. I had
asked for coarse sand and that is what was delivered. Due to its varied
particle size and the sharpness of it, I thought that  it would be great for
cobbing--until the feet got raw and bled.

here) and is anywhere from a fine powder to a course sand in size.
