How to Convert a Knit Cowl Pattern from Sport to Worsted Weight Yarn

I am often asked about yarn substitution for patterns. Sometimes its quite easy, and other times it is more difficult. Here is an example of when it is easy.

I took a simple knit cowl I designed in sport weight yarn and converted the gauge to make it in a worsted weight yarn.

The original cowl was knit with Be So Sporty Yarn on a US5 (3.75mm) 16" circular knitting needles. The gauge is 5 stitches per inch. For a 20" circumference cowl, the number of cast on stitches is as follows: 5 x 20 = 100

In order to convert the pattern for a different type of yarn (yarn substitution), you need to do a gauge swatch. I cast on 16 stitches and worked several rows with worsted weight yarn (Be So Bold) and US8 (5mm) circular knitting needles. I measured the width of the swatch to be 4" wide. I divided the number of stitches by the width in inches to get my gauge: 16 / 4 = 4 stitches per inch. For a 20" circumference cowl, the number of cast on stitches is as follows: 4 x 20 = 80

Here is a video demonstrating how I did the conversion and how to knit this pretty lace patterned, worsted weight cowl. Below the video are the written instructions for both patterns.
