Here, a magical, billowy tent sets the stage for dressing up and making music. Dolled up in play clothes, hats, and paper leis, kids can pound on drums, tootle on harmonicas, rattle maracas and tambourines, and dance the day away. To make the tent, fold a sheet lengthwise over a clothesline hung about 5 feet high. Clip the sheet to the line with clothespins. Then, run two more clotheslines, about 3 feet high, on each side of the first one. Drape the sheet sides over them and clip them with clothespins. Spread a sheet or blanket on the ground, set out the supplies, and let the kids make some noise.
