How to make a Yoshi costume

Step 11 Tail + Backpack

For the tail I got two large pieces of cardboard and cut half a line (is that possible) down the middle of each to put them together, then wrap it in masking tape to paint the top half. Then I wrapped it in glad wrap for extra protection. This was the night before I needed it so I was pretty rushed, there are probably much better ways to achieve it.
In the morning I stapled loops of elastic around where the legs and waist would go. The waist one kept snapping so I eventually just tied knots.

For the saddle I just covered my backpack with the orange cover of one of the cushions I borrowed and held it with staples and safety pins.
