Knitting in the Round– Magic Loop by Knitpicks
Measure length desired. Anywhere between 23″ (58 cm) to 26″ (66 cm) should work.
With one strand each of an eyelash yarn and a sport weight yarn, knit a swatch.
Determine gauge or number of stitches in a 4″ x 4″ (10 cm x 10 cm) square.
Determine the number of stitches to cast on. You need some math to accomplish this:
(Desired Length in inches x number of stitches in 4″) divided by 4″ = Number of stitches to cast on
(Desired Length in inches x number of stitches in 10 cm) divided by 10 cm = Number of stitches to cast on
Using a set of 16″ (40 cm) US 15 (10 mm) circular needles cast on calculated number from step 4, join ends to knit in round and knit neckwarmer until desired width.
