Last week I had to take a personal day and had laid out things for my sub as best as humanly possible. As I went to flip the lights off something caught my eye and I had a moment of sheer terror. I had left my "good sponges" out in plain sight. Good sponges. What if my sub wasn't sponge-worthy? I can't be alone in the coveting of a good sponge. Here's the hierarchy as far as I know it.
Level 1. Brand new sponge. Glorious and yellow from the cellophane packaging. A new sponge gets cut into thirds or sometimes quarters right from the package. (Sponges don't grow on trees, y'all.)
This sponge can only be used for printmaking. Once it mops up a table or something with glitter, it's all downhill.
Level 2. Once students have misused a printmaking sponge it can be used for moping up small spills by the teacher. This sponge is still too pretty to be given directly to students.
Level 3. Your everyday free range sponge. This can be used by anyone for just about anything.
Level 4. This sponge has seen better days. When wrung thoroughly the water from this sponge is always slightly gray and smells of gym socks. It can be cut down into shapes for sponge painting or stamping. Several of them can be used as packing peanuts for taking home clay projects.
