Smells like fall today as I use up the last of the 400M from Testfabric. These sponges were packing from some electronic gadget. Makes me wonder just how much dye paste made it onto the fabric.
You can see in this next picture that a lot of the vibrancy of these pieces faded away as they dried. That reminds me, I'm going to go upstairs right now and "wet" one of them with acrylic medium to see if the color depth comes back.
