Sweet Summer Baby Blanket KAL: Cables on Seed Stitch Square

I’m joining the Sweet Summer Baby Blanket Knit Along with the pattern for the Cables on Seed Stitch Square. This pattern uses a simple cable on a seed stitch background to add lots of texture. This pattern includes a video tutorial for the C4F cable (also known as the 2-2 LC, or the 4-stitch left-leaning cable).

  1. I plan to use that pattern for a hand knit towel. Thanks for the gauge so I can create my own pattern.
