Chalkboard Pi Spiral T-Shirt – 3.14 Math Art Desig

Chalkboard Pi Spiral T-Shirt – 3.14 Math Art Desig

This chalkboard-style Pi Day t-shirt features the Greek letter pi (π) at the center, surrounded by a spiral of pi digits (3.1415926535897932384626433…). The hand-drawn chalk illustration gives a playful math classroom vibe with high-contrast white-on-black artwork that prints beautifully on apparel. Perfect for Pi Day (March 14), math teachers, students, STEM clubs, and anyone who loves geometry and number patterns. A great gift for mathematicians, engineers, and science lovers. Looks awesome on t-shirts, hoodies, stickers, mugs, and posters.

Basic Dark T-Shirt, Navy Blue, Small
I found the shirt quality itself to be well made. Unfortunately I found that the image quality of the artwork is low resoultion. So the art and words aren't as clear. I probably wont buy another shirt to be honest, but I'm glad I supported the podcast of which I'm a fan of. I was just hoping that for the price I paid, it would have been of better quality.
