If you want to have a bash at making these stretchy jaws, here's how! First of all, you'll need a large, strong piece of card. Draw around a 30cm ruler six times, leaving a big gap between the last two, as you can see here. The next thing to do is draw around the ruler again, onto a sheet of paper. This will become a template, so cut out the resulting shape. Fold the piece of paper in half, then fold it again lengthways. Cut a snip on the corner of one end, and another snip about 2cm from the other end. You should now have a piece of paper that looks something like this. The grey lines indicate folds and the black squares show holes. Now, take a pin or a drawing pin, and place your template on the piece of card that you drew onto. Using the pin, carefully punch through the template into the card. Make three holes in two of the ruler shapes, and two holes in the rest. It's now time to draw the upper and lower jaws. Draw these above the two ruler shapes where you left a gap on the card. The design is up to you, but you could follow our templates. Click on the one you want. When you're happy with the facial features, cut these all the other card strips out. You then need to paint each of them. Poster paint or acrylics work equally well, but be careful not to clog up the holes you made earlier. Assembly time now - and it's important to get the order right. Take the top jaw, followed by a three-hole strip, followed by a two-hole strip, and stack them one on top of the other. Then the bottom jaw, a three-hole strip and a two-hole strip, and again - stack them on top of each other. Now lay it out - bottom jaw first, with the jaw on the left, then the three-strip in the middle and the two hole strip on the right. The top jaw goes on top, followed by the last three-hole strip and the last two-hole strip on the right. And finally, connect up each of the pieces with paper fasteners. And that's it - finished.
