Aquapaintings are a unique, reusable painting activity! Water and a paintbrush are all that's required. Aquapaintings are intended to be enjoyed by persons of all ages and ability levels, and feature appealing real-life images. With a paintbrush, simply apply water to the sheet and see the image instantly appear. Once finished, you can use the image to facilitate conversation. After each use the image will slowly fade away until it’s a blank canvas ready to be reused! Includes 2 each of 6 different image mats that measure 8-1/4” x 11-1/4”.
