1: So first cut your cereal box to the size of square you desired:
2:Them trace light lines across the corners and then from the center to the corner find the middle point market connect all fours to get a center square:
3: Cut the diagonal lines that are outside the square and bend the right side corners only:
4: In the middle poke a hole with your nail and if you happen to have a double stick tape put some in the center to help you hold your corners. On another note if your nail is the same nail as mine I recommend to just use one bead, you'll see why later:
5: Then Bring your corners to the center to poke holes on them, you can do it with the nail or the x-acto knife:
6: Now unite all corners with your nail, then bring it down to the center hole of the soon-to-be pinwheel:
6: I recommend to get someone to hold your brush while you hammer (gently no need of force) I ended up removing a bead because otherwise my pinwheel would not spin and that's not fun:
7: Tada! spin it, spin it until it feels loose and is ready!!!! decorate it anyway you can, and make it pretty.
