Here I am cutting the trash can. I didn't use a pattern or anything for this, I just cut the bottom out of the can first and then got inside it. I completed the design by figuring out which pieces needed to move so that I could crouch down inside the trash can. It took only a few cuts to make arm flaps, a head flap, and a back-flap.
Total project time so far, about 20 minutes.
This sure was easy. Here is the finished trash-can costume. You can see the head-flap and the arm flap. The back flap is on the other side.
Here I am hiding in the trash can. If I crunch down really well, I can pass for a trash can. Also, I can see out of the top flap.
The neighborhood kids don't stand a chance.
Here I am scaring you!
Here is the original concepts sketch for the trash can costume candy trap. I figured I would save it so that you could see how the idea started.
