About This Design

Pi Day PiDay Chalkboard Education T-Shirt

Pi Day PiDay Chalkboard Education T-Shirt

It’s not irrational to know your Pi. Teacher posted the most significant digits in the circle shape of Pi along with the symbol in chalk. Celebrate Pi Day every March 14, which is also the birthday of Albert Einstein. Do you suppose this is just a coincidence or is it the secret power of math? Pi is one of the most important numbers in mathematics, so memorise at least 3.14 or 3.14159 before you dig into your pi day pie on PiDay.

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.

this was good quality and perfect colour. Printing was great although when we all opened our secret santa gifts one of the other mechanics commented whoever got that for him missed out part time after the word mechanic Sorry I don't have any photos
