It doesnt look busy now, but it was, at least 500 kids past though our painting on rocks. This is Emily my wonderful daughter that helped me out, whew, I learned many lessons. The first one being kids especially little kids are very happy painting anything, rocks included. The second one is next time bring a tablecloth. I guess the last thing is people in general are very nice and forgiving, one parent was upset that I used acrylics that wont come off his shirt, until I explained if I used temperas they may not come off his car seats. One big learning curve, we had a wonderful day all in all. Came home played scrabble, she beat me, for the second time, a great day. Time to bone up on my scrabble....
