At first, we just wanted to draw some lines on the space to see if it's possible to draw a bigger star. Then, we found out there are more space around stra "a". So, we tried to conect each point of star "a" and made a bigger perfect five-point star. It works!
In the second picture, there's a star around star "b" because we also found more space there. But when we drew it, one point of the star out of the foul line. So, this puzzle just has one solution.
