  • Quilting - pictures of some of my mathematics-related quilts. Check out the one about MSRI 2002/03. Apparently the quilt got lost during its move back up the hill! Sigh!
    TUBE PIECING: For the last few years I have been developing a very fast, efficient, and accurate method for making quilts. I call it tube piecing: it is to strip piecing as strip piecing is to traditional piecing. For example, I can make a quilt top with twelve rows of triangles, each row having nine red triangles pointing one way and nine yellow triangles pointing the other way, all sewn together with 32 seams only! I have many other impressive shortcuts. At the end of June 2015, my developing book has 370 pages. The book contains many concrete examples, but also mathematical formulas for changing sizes and angles. I plan to eventually set up a web page for tube piecing. Please let me know if you are interested in testing (iswanson@reed.edu). Only standard quilting gadgets are needed (rotary cutter and mat, sewing machine, iron, fabric, thread).
