The bus seat sweater is a perfect example. To re-create the seat as a sweater, Dodd measured each part of the seat’s pattern and took a photo for reference. She carefully found the diameter of a circle on the seat’s design. She also counted how many rows and columns of circles were on each seat. Dodd then used grid paper to design the knitting pattern. Each square represented a single stitch, or loop of yarn around a knitting needle. The average sweater is made of about 75,000 stitches, so that meant a lot of grid squares.
And that was just the planning! It took some trial and error before Dodd was happy with how her pattern looked when knitted. “My first attempt didn’t look quite right, because the circles looked more like squares,” Dodd says. She changed the color of the stitches at each circle’s “corner” to the background color. “Presto! Circles,” she says.
