I made this compact hotplate for my kids. Both of them like cooking. They have their menu list and carefully put down my orders. They are always around the hotplate cooking something. I like it too, because it fits well in the toy box or on the shelves stays almost unchanged with the time. And I made it a year ago.
We used a big piece of corrugated cardboard, folded several times. We wrapped it with a black piece of cardboard paper and put scotch tape on the edges to preserve them for a long time. The hot plates are two cardboard circles covered in red paper.
Use black marker to draw the details which will make the kitchen appliance look authentic.
