This is a Loom Knit pattern. Any loom can be used so long as it has multiples of 8 pegs. The size can be adjusted to suit an adult or child.
The sample was made up using the Martha Stewart Knit and Weave Loom with 48 large pegs.
In the sample I used Rowan Cocoon and it came out really soft. The loose knit shows off the fluffy nature of the yarn. Any chucky or super-chunky yarn can be used, although thicker yarns will result in a tighter knit.
The hat if made up as per instructions, comes up quite large and has a nice snuggly, slouchy fit. perfect for chilly days!
