This pattern is super simple and yet super customizeable! You can knit it to be fitted or knit a size or two up so it’s more of a slouchy blanket fit! There is also an option for a sleeve modification added to the pattern in case you want to up the warmth levels.
To knit this pattern you will need to know how to do a provisional cast-on, knit, purl, place live stitches on hold on scrap yarn, blocking a garment and mattress stitch. I provide in-text links to resources for most of these techniques.
