Did you do it? Notice that the angle of the cut changes the shape of the star--a less acute angle makes a "fatter" star, a deeper angle makes a star with skinnier arms like this:
See how the angle on the yellow paper is steeper than the one I cut for the silver star? It comes out looking like the photo below:
And what about that blue paper with two lines on it? Guesses? Right--an outline star plus a smaller bonus star...
And you needn't be restricted to straight lines. A curve with a nick at the top gets you this:
|Springtime Cherry Blossom|
|We are the World...|
|...We are the Children...|
And feel free to draw your own shape across the middle of the 10-fold! I tried drawing holly:
|Merry Christmas to All|
Mata asobou, ne!
