I was going to take a big, thick piece of polystyrene to puppet school tomorrow. It's to be a river bank in which we will stick our very excellent pipe cleaner bull rushes in order that the baby Moses will have somewhere to hide. I meant to buy green spray paint but completely forgot. I'm off to school early in the morning and was in my workroom puzzling about what to do why my eye fell on some vegetable net the fruit shop had kindly given me. It included some green net bags of just the right size. Three of those, one on top of the other and voila, instant grass, just add bullrushes!
