Once the hands have dried. I freehand trace around the edges so they know where to cut. As they cut out their hands, remind them to put their names on the back of each one. You could also do this for them before they start to cut.
Now, for those of you who want to skip the whole paint thing all together, you can have your kids trace their hands and cut them out. This is a hard skill. They need to work with a friend, tracing each others hands.
Now all you need is the body part. I printed mine on construction paper. I trimmed it to fit into my printer. You can read about that here in Printer Tips and Tricks. To download my free butterfly handprint art body template just click the picture.
Once you've glued the hands to the back, add some googly eyes and chenille stems for antennas and you have an adorable butterfly handprint art project to hang around your classroom.
