Step 3 Make the Torso Box Thingy!

Yes, you too can have your very own torso box thingy. This is probably the simplest bit.

Make sure you have the right measurements for your torso. "Ducky Boy" managed to totally screw up his measurements, and had to do them again.
Sigh.

Anyway, slit a cardboard box so it's a flat piece of material. Use a yardstick to measure your torso height's length along the cardboard and draw a line. If that didnt make any sense; draw a rectangle the height of your torso on the cardboard. Add an inch or two just to be sure.

Now find your torso width (left to right) and depth (back to front). Mark a line at the torso width on the piece of cardboard. Measure from this line your torso depth, then your width, and depth again. You should have four lines. Cut along the outlines, and score along the three internal lines. Now fold it into a rectangle, and tape the edge.

We had to reinforce the top with bits of cardboard to make it stronger. Whatever floats your boat.
