When I looked ahead and saw a week of rainy weather last week, I put my creative brain and came up with some interesting alternatives for the kids. One day, the girls and I made 'rain-drip' art. First we colored with markers (Crayola washable) on fingerpainting paper. Then we bundled all up, and went out in the rain with our paper. We held the paper under places that were dripping, and wiggled the paper around to make water paths through our many colors. Then we dashed inside and put them on the counter to dry.
It was a fun project. Nothing to put in a frame, but maybe something to use as stationary? And most importantly, the rain didn't beat us today.
