Free Knitting Patterns

Free Knitting Pattern for EZ 100th Anniversary PI Shawl: Camping

EZ 100th Anniversary PI Shawl: Camping

This shawl by Mwaa Knits is a tribute to Elizabeth Zimmermann who developed an easy, versatile, and innovative idea for creating circular shawls using the geometry of Pi–the relationship between a circle’s circumference and its radius– with just 6 shaping rounds. This tribute design was published in 2010 in honor of the 100th anniversary of her birth on August 9th, 1910 (8/9/10). Modifications to Elizabeth’s original design have been applied so that the lace design stitch repeats and the number of rounds are multiples of 8, 9, and 10 (the numbers in her birthday). The camping theme to the lace patterns is in honor of Elizabeth’s love of camping.

Free Knitting Pattern for Crystalline Symmetry Sampler Scarf

Crystalline Symmetry Sampler Scarf

This double-knit scarf designed by a mathematician knitter Susan Goldstine to demonstrate 9 of the twelve possible plane symmetry structures described by mathematical artist Mary D. Shepherd in her book Making Mathematics with Needlework: Ten Papers and Ten Projects . (A more detailed explanation is available on the pattern page at Knitty.)

Free Knitting Pattern for Summation of i Mitts

Summation of i Mitts

These fingerless arm-warmers have stripes that conform to the formula for the summation of i (between 1 and 9) – the formula used to compute the summation of the integers between 1 and 9. This formula is n(n+1) /2. So the summation of 1 through 9 would be 9 (9+1)/2 = 90/2 = 45. The mitts have 9 blocks of 10 for each of the integers and each block divided in 2 stripes with increasing by 1 row in one color and decreasing in the other color to represent the integer. Adding the rows of each color will give you the summation.2 sizes. Designed by Tasia Block

Her recipe used  the geometry of Pi–the relationship between a circle’s circumference and its radius — to create circular shawls containing only six shaping rounds that makes it easy to add incorporate many lace designs, as many knitters have done. Her original design included 2 patterns – a basic design and one with floral and diamond lade motifs.
