This pattern is worked on dpns (double-pointed needles) to be worked in the round to be seamless. It calls for two types of DK weight yarn to be knit together as one but you could also use any kind of worsted weight yarn of your choice. Very simple pattern just need to know how to knit and purl on dpns. The pattern is written in 4 different sizes. follow the size you desire based on parenthesis. Example: (Kids Small) (Adult Small) Adult Medium (Adult Large) will correspond with the number of stitches needed, so the pattern will look like this: Cast on: (80) (84) 88 (94). You choose the size you are making and follow along. The (80) would be Kids Small. The pattern shown is Adult Medium, which is why that size is not in parenthesis. Hope that makes sense.
