This is made from bits of a kitchen sponge, whizzed up in a blender, coloured with ordinary house paint kneaded through, dried in the oven and then ground again in a little electric coffee grinder.
It's not utterly worthless, but I was hoping for a smaller grain size than this. Also, the sponge is yellow, so that affects the final colour.
As it is, this is really no better than the sawdust flock I made some years ago. In fact, it's probably a bit coarser.
I'll give it another go with some white open-cell upholstery foam, which should colour more accurately, and will hopefully grind down to fluffier bits.
