Tissue paper art...fast, easy, cheap.....and soo colorful and mood lifting. Google it to get a ton of ideas for tissue paper....
(I remember that my kids used to do it in art class at school). I especially loved the glass bottles that were turned into beautiful vases and objects of "art".
Making sand candles is one thing that I did with the kids...one year when I had very little money....terrific fun (guys, especially, seem to like this one).
