Big Bugs SYMMETRY. Fold a page in half. Draw the bug on one half with oil pastel. Fold paper and press firmly to reveal the other half. Trace those lines: perfectly symmetrical drawing. Now paint in cheerful colors. Check the post for more really cool examples of bugs, butterflies, other things.
Paste the string or yarn on the cardboard. Once the glue dried, place a piece of foil on top and rub with your fingers until it is adapted to the designed shape. Signing the foil with a little tape. Finally painted with permanent markers.
