First, you need to get a lid of a box. Then get a marker and draw the shape you want your shield to be on the TOP part of the lid. Next, get a knife so you can cut out your shield. Now cut out a long , wide strip off of the lid of a box with a knife. After that, bend the strip you cut. Next, get the bended strip and tape it to the back of the shield. Now you can draw stuff on your shield and you can color it if you want. I hope you enjoy your shield!
