Start with the end of the roll, the last 12 inches of tape that has the cardboard backing. You may need to trim to make sure you have a nice straight edge. Fold it over to make a triangle, flat edge to flat edge.
Cut out your triangle.
Next you want to seal your triangle. (This is where some pre made duct tape strips are helpful) Use the half on/half off technique for closing the edges of your triangle.
Use your scissors to trim off the bottom (long) edge of the triangle. You have now created the basic corner biter. You can stop here or continue to decorate.
I'm going to turn mine into a little monster. First, I'll make the teeth. Take a 1-inch piece of white duct tape, fold it over onto itself , leaving about 1/8" inch of sticky. Using your scissors, cut some jagged edges up and down along the line.
Now to make a tongue. Cut a 5-inch long piece of red duct tape. Fold it up onto itself, again leaving a little sticky edge.
I made a long rounded tongue, but you can cut whatever shape you desire. It's your monster!
Using the same technique as the last few steps, take a 3-inch piece of yellow duct tape. Decide what size or shape ears you want.
Fold the piece in half with the sticky side facing out. Cut out your two ears.
Now for some more fun monster accents. Put your white strip of tape over parchment paper, half on /half off, and cut out your eyes. With this technique you end up with two identical circles. I repeated the same step using blue for the inner eye color.
Now, let the fun begin! We are ready to assemble our monster face! Apply the ears to the top of your corner biter, then maybe some inside ear-color (I did it in red), next the eyes and so forth ...
Once the face is complete it's time to assemble the teeth and tongue.
Using the sticker side, place the teeth inside the mouth. Secure that with a small strip of tape.
Last but not least is that long red tongue. Stick it inside the mouth like you did the teeth.
All done! Make a bunch of different creatures or a batch of the same creatures with different faces.
