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.

Pythagorean Triple Wrap
Rectangular shawl featuring mitered corners, textures, cables, and lace with a construction that shows how different geometric shapes join together to form another geometric shape inspired by the basic mathematical concept “Inscribed Square in Right Triangle”. Great stashbuster! Designed by Naurid Kashpia Senjuti for Knotions.
2-color, reversible infinity scarf that can be worn as a loop, doubled as a cowl and also pulled up to be a hooded scarf. The pattern harmoniously blends two colors using the Fibonacci numbering sequence in the row count. Both colors fall into an attractive arrangement, found often in nature, starting with one color and ending with the second color. (A Fibonacci sequence is "a series of numbers in which each number is the sum of the two preceding numbers. The simplest is the series 1, 1, 2, 3, 5, 8, etc."). Designed by Diane L. Augustin. Aran weight yarn.
These fashion doll dresses are more than pretty outfits. They are designed using the mathematical Fibonacci sequence and are great for inspiring interest in mathematics in doll-lover and knitters alike. (A Fibonacci sequence is "a series of numbers in which each number is the sum of the two preceding numbers. The simplest is the series 1, 1, 2, 3, 5, 8, etc."). Designed by Woolly Thoughts. DK weight yarn.
Golden Mean Mitts
These fingerless mitts feature the golden mean with spiral on the top and on Fibonacci numbered stripes on the palm. These mitts depict the classic geometric representation of the golden ratio. From Wikipedia: Two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities. Designed by Buús-Zsohár Anna
Anamorphic Fibonacci Socks
Stranded socks with a design using a Fibonacci sequence in a trick perspective. (A Fibonacci sequence is "a series of numbers in which each number is the sum of the two preceding numbers. The simplest is the series 1, 1, 2, 3, 5, 8, etc."). 3 sizes. Designed by imawale imawale. Fingering weight yarn.
These entwined rings, inspired by mathematical concepts, can be worn as a cowl, necklace, or headband. If knit flat and small, they even make a baby toy. Borromean rings consist of three circles in which no two of the three rings are linked with each other, but nonetheless all three are linked. Designed by sarah-marie belcastro and Madison Stuart. Pictured projects by smbelcas, dmwoodman, Animae424, and smbelcas again.

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
Klein Bottle Hat
This hat is a folded representation of the Klein bottle that’s a atwisted torus (donut) in the same way that a Möbius Strip is a twisted loop so it has just one surface. Designed by Marie-Christine Mahe for Knitty. Pictured project by TheresaMarie1972
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.)

Lina Wolf’s fractal wrap / shawl / scarf was designed to honor Benoît B. Mandelbrot who developed fractal geometry and the Mandelbrot set that is partially pictured in this double knit shawl. Lina’s original design included Mandelbrot’s name. Pictured project by SINessi
Math Pencil Case
This zippered bag is decorated with mathematical symbols including pi.
Mathematical Underdogs Coffee Coasters
6 coasters including Pi, Phi φ (golden ratio), Zero 0, and (not pictured) Epsilon ε (a positive number tending toward but never reaching Zero), e and sqrt(-1). Designed by Lina Wolf. Pictured project by helenbee21
The perfect gift for the tech lover in your life, this scarf incorporates binary code into stranded colorwork knit as as a tube so the reverse is hidden. You can knit random 1s and 0s or use a binary translator to create a message for your scarf like “I love you” or the recipient’s name. Ravelrers have adapted this pattern to hats, mitts, cowls, baby clothes, and more. Designed by by Christine Dumoulin for Knitty Pictured project by Neetstoo who knit the names of her family in binary in her scarf.

Patterns for Purchase
Shawl or scarf knit with fractal structure. Fractals are geometric shapes that repeat their overall shape in the small details. Frattali is a large stole worked in the round, super easy to knit, and the fun fractal structure makes it interesting to knit and wear. Using yarn with long color changes accentuate the shape. Designed by Martina Behm. Perfect gift for math lovers!
Ten patterns for knitted cushion covers and two crochet patterns illustrating mathematical concepts. Examples: Square to Eternity (top right) - Triangles are added to create a new square. Each new square is double the area of the previous square. Have It All Ways (row 5, right) - All the permutations of four colours. Wreck Tangled (row 3, right) - Each rectangle has the same area and the total of their areas is the same as the area of the background. Designed by Woolly Thoughts.
Double Base Blanket
This geometric design is a representation of binary numbers using simple garter stitch, using any yarn and needles. Make it any size from baby blanket to king-size bed. It can be made in two or six colours in any weight yarn. The design is by mathekniticians Pat Ashforth and Steve Plummer who include an explanation of the binary numbers represented.

Original Pi Shawls or Blankets
Elizabeth Zimmerman first published her easy, versatile, and innovative idea for creating circular shawls in 1987. 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. Pictured projects by rubycat who added extra repeat of 48 row section and a different lace border, and yarnstormer. Included in Elizabeth’s book, The Knitter’s Almanac.

This design by woollythoughts is nowhere near as complicated to make as you may think. If you can knit garter stitch, you can do it.
