Idiom

Second night of school. We're in the first years' painting studio so we get to marvel at the mess they make. What would their mothers say? But a fine night illustrating idioms picked at random. The challenge being not to be completely literal but to convey enough information that someone could work it out. Also a slightly odd exercise since they're English phrases, the tutor's German and apart from the few native English speakers, the class contains one Romanian, one Chilean, another German, one Spaniard, one Czech and someone from Falkirk.
