How to make a paper pinwheel?

2. Fold this square of paper along the diagonal. (A square has two diagonals, both should be folded)

3. Use a knife to cut through the folds (Note! Should be cut from the inside out, and the scratch should be shorter than the crease 2 to 4 cm center position is retained, do not cut open)

4. At this point, the paper becomes four central adhesive triangle, the emergence of eight corners. Every other corner of the roll a corner. If you rolled ∠1 then you have to roll ∠3, ∠5, ∠7, if you rolled ∠2 then you need to roll ∠4, ∠6, ∠8. Then, fix it with a peg in the center.

5. Then put the paper through the pegs through the sorghum stick (that's the stick on the broom, one will do)

6. Finish!
