The summer before last, I had the great fortune to send my son to the Hampshire College Summer Studies in Mathematics program( www.yp17.org ) for the second time. He had a wonderful time learning and playing with mathematics, and I got to hang out with sarah-marie belcastro ( www.toroidalsnark.net) , a Math professor at Smith College, who is co-director of the program. She was knitting a magical toroidal object with teeny tiny double pointed needles! We got to talking, and I mentioned my interest in knitting and quilting. She was writing a book about Math and needlework, and I enthusiastically offered to be a pattern tester. Well, several months later, she sent me the patterns for two mobius quilt designs. I had a blast constructing these, and for good measure, made a quilt of a "squashed dodecahedron"...I sent them to sarah-marie, and now, I'm thrilled to hold the book in my hand! My quilts are on the hard cover, and you can read the directions to make these in the book! it is available from Amazon, or directly from the publisher, AK Peters ( www.akpeters.com ). The directions for making your own knitted torus are there, plus fascinating papers on mathematics as it relates to needlepoint,blackwork embroidery, quilting, knitting and crochet. Truly a feast for those of us who love mathematics and needlework.
