This pattern includes five downloadable pdf files, one for the written directions, and four pdf files for colorwork charts (left mitten, right mitten, thumb, and boarder). This pattern calls for 2 differently colored skeins of the Woolike yarn by Loops and Threads, however, another size 1 yarn can be used. Woolike has a lot of yardage and I use about a 4th of each skein when knitting one pair of mittens, so one skein of each color is plenty. Please use the end on the outside of the skein to save yourself hours of untangling. This pattern calls for US size 2 double pointed needles and is worked in the round. You can use size 1 needles if your hands are smaller than a women’s medium.
