Waiting for my husband outside Home Depot after a stop for lunch at McDonald's, I sketched my iced coffee cup. I only had a pen with me (and a very loose, black ink in it too) so no erasing. I am not comfortable without being able to erase but I think it's recognizable!
When I've drawn something like this I see if it fits an EDM challenge. There are so many of them I oftentimes find one!
