I am doing a batik project with my Year 1/2 class. They have drawn their designs on paper, transferred the design onto cotton material, and put a thin layer of flour/water mix along their design. The flour and water 'goo' has dried and they are now ready to paint. I made one as an example and coloured my picture in using normal poster paints from the classroom, then picked off the flour when the paint was dried.It looks effective, but I was wondering if there are better paints or techniques I could use at this stage. I don't really want to use fabric dye in case it gets on their clothes (despite aprons!) However, we could do this under supervision. Perhaps I could water down the paints to make a 'wash'? The theme is 'under the sea' so their designs are fish, boats, crabs etc. Any ideas welcomed - art is not my area of expertise!! It's been a lovely, peaceful project to do so far and I'd really like them to feel proud of their finished work.
