Painting with tissue paper

We used tissue paper that bleeds, you can find it at a teacher's store or craft store. We cut the pieces of paper into small squares, we traced a flower you can make anything we've done a hot air balloon before that the children enjoy and they come out beautiful. You need vinigar and a brush. The child wets the brush and paints the paper with vinigar and then placed the piece of paper. They should brush some more vinigar on top of each piece so they are nice and wet. Then you set it over night to dry. I the morning you brush off the tissue paper and the colors have bleed through. They look just like water colors and the children love doing it.
