When you have finished putting the dye on the first side, turn the whole thing over. This will be easy to do, if you just flip the plate over onto another paper plate with clean paper towel all ready for you. Throw the first paper plate and towel away (clean up as you go along whenever possible) Apply the dye on this second side in a similar manner. If you are making the rainbow swirl, you need to be sure to put the three colours behind the same colours you used on the other side (i.e. red behind red, blue behind blue, etc.) If you don't do this, you will not get a rainbow spiral, but a sort of rainbow spider pattern (which is quite nice actually!)
