Phi Star Tee

$25.43 SGD

The Phi Star is the core logo of Greyheart Goods. 

In most design software, choosing a star pattern will produce a five-pointed star that is equal in width and height. That's not actually how the dimensions work. A true star that contains the golden ratio is wider than it is high. 

See if you can figure out how many times phi is used in this design!
