An appreciation and demystification of mathematics is a common thread that runs through my art. Drawing, bronze, painting, glass and photography were mediums I had investigated before 1980. After 1980, I settled on fabric to tell my mathematical stories. The topics I have quilted include early mathematics from 2,000 B.C.E. to mathematics of the present time. During the last 40 years, I have generated 66 quilts. Most of the quilts are sewn by hand. Very recently I made a book of the all the mathematical quilts. This book titled "4,000 years of Mathematics in Quilts" shows quilts from each time period. The most recent quilt that was added to this collection is "Baudhayana" from 800 B.C.E.

\[ \sqrt{2}\approx 1+\frac{1}{3}+\frac{1}{3\cdot 4} - \frac{1}{3\cdot 4\cdot 34} = \frac{577}{408}= 1.414215686\ldots \]

is correct to 5 decimal places.
