About This Design
Pi Day PiDay Chalkboard Education Stone Coaster
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 memorize at least 3.14 or 3.14159 before you dig into your pi day pie at your PiDay party.

Limestone Stone Coaster
Creator Review
Beyond expectations, the photo was perfectly reproduced on the stone and the stone texture made it something special. A quality product. As a photographer, I am very aware of print quality, and this product clearly met my high expectations.

I have received many compliments on these coasters and they have withheld very well with extreme heat from a mug and the condensation from a glass without ruining any of my wood surfaces. The print actually turned out exactly like the photo.

I had been looking for coasters in stores for a while now. So glad when I found these coasters. I made a set of six using my own photos. The travertine was exactly what I had wanted for the "old world" effect and adding my favorite photos made them simply perfect! The quality of the photo on the travertine coaster was even better than I had expected.
