Rug Design Program

Kate asked why a rug design program for rag rugs? For the math challenged it makes designing a Diamond Rag Rug much easier. See the article by Debra Sharpee and Judith Yamamoto in Handwoven, Nov/Dec 2001. Remember, I've never done one yet, but here's a snip from the program documentation

Diamond This allows you to design simple diamond rugs wherein the principal variable is the ratio of the first repeat to rug width. Using the button controlling this ratio (fourth button down on the left), try various values to see the effects. You will get best results if you keep the ratio close to an integer (e.g., 1.97 or 3.04)

Shwoosh The Shwoosh factor makes the ratio of first repeat to rug width change as the rug is woven, producing curves.

ZigZag In a non-Shwoosh rug, this allows you to make the ratio reverse one or more times during weaving � making interesting zigzag patterns. �Reversing� in this context means making the ratio fluctuate around the nearest integer (e.g., 1.95 to 2.05 and back to 1.95).


  1. Ooh I've been wanting to make rugs like those for a while. Are you going to do one? Can't wait to see how it turns out.

  2. Computer makes pretty pictures. I like pretty pictures. (As I was saying to Joe this morning, I am highly amused at how mathy weaving can be despite my "Math is hard" Barbie attitude.)
