Now you’re ready to start adding paint to the methocel mixture. To do this, take your paint brush and gently drop your first color on the surface of the mixture. You can place your drops at random or in a pattern to create different effects, but keep in mind that the more paint you put on the water’s surface, the less pastel your print will turn out. Don’t be shy if you have a large container; it’s going to take more paint than you think to cover the size’s surface completely. If you’re using a small container, take care not to add too much paint – if so, you will lose the surface tension of your size and your colors will sink.
