This quilt contains an infinite number of digits of tau (2pi)...at least conceptually. In practice only about the first 5800 are actually readable, and after about 10,000 they have gotten so small that they are less than one stitch wide. The last infinity digits are represented by a single stitch. The purest form of this quilt is round, but we also have a square version (same circular design, but with the corners filled in with a simple pattern).

Unlike most of our other quilts, this one is made with wool batting, so it is thinner and drapes more like a traditional quilt.

We also have a less extreme (but thicker and puffier) regular tau quilt with about 180 digits of pi..
