Is apparently just about hanging things on brick walls
Excellent idea! How well does the chalk stay/wipe off?
you really need to use a little water to get it off otherwise it leaves a nice smudge. since it is chalk it stays on until it gets smeared or wet which of course happens all the time. you can also draw well on the etched surface with a pencil but it is not a great color to show up on beer. that also can be wiped off.
i'm not here right now but leave a message and i will get back to you as soon as possible.
