This is a really lovely project that will be perfect for the work I am doing with young children! I am an outdoor classroom teacher working with children ages 2-5 years old. Right now we are creating art that commemorates the monarch butterflies that visited our classroom in the early fall of this year. I can imagine the beautiful images of monarch butterflies and caterpillars that the children are drawing and painting duplicated on fabric using this process! I am imagining that it is so much better than the computer printout/iron-on method, I am wondering what types of materials can this be used on? http://reflectionsgardenclassroom.wordpress.com
