Pee Towels

You might remember Amy Rawson as the creator of the felted Cthulhu Santas we feature during the holidays. Her latest project is the Pee Towel, which arose from her day job as a lab tech. Specifically, from urinalysis.
Part of urinalysis is a microscopic examination, and one of the microscopic elements we look for is crystal formation. Urinary crystals result from a supersaturation of the urine with some particular substance. That substance can precipitate out to form distinctive crystals.

One kind of crystal inspired Rawson to design a fabric featuring her drawings of calcium oxalate, from which she made kitchens towels called Pee Towels! You can get yours in her Etsy shop. Read more about urinalysis and the creativity it inspires at Rawson's new website.
