The kids came up with several very different and really good suggestions per class, but unfortunately we could only choose a few of them for execution. This one wasn't chosen.
Last week we used an overhead projector to make masks to help us paint the murals (because of several practical reasons we couldn't use the projectors to sketch directly on the walls)
and then we cut out the masks
Tomorrow is the DAY: we will paint the 5 murals. Cross your fingers!
