Ok -so I was surfing around on youtube and checking out some gardening links. I found some videos on straw bale gardening. Very cool idea. These would make a great kids garden. Maybe a small maze with straw bales and plants growing on the bales. Maybe a little "playhouse" made of straw bales with little rooms ( no roof) and plants growing on the sides. Good project for schools and summer camps. No digging , less muddy, very architectural with potential for design ideas!
