This pattern is knit in the round. It is a regular size but can be adapted by increasing or decreasing stitches at the beginning of the round by 8 to cater for the chart pattern. You will need to make relevant adjustments for the heel and toe. The pattern calls for 9 inch circular needles or needles of your preferred sock knitting method. I find using the circulars is easier when doing colour stranded work. It also requires stitch markers, double pointed needles, darning needle and scissors. The yarn used is in balls of 100g and will leave lots of yarn left for more socks or another project. My socks are done in groups with the same colours used on different designs. This is part of the Phone Doodle range. I decided to do this as I suffer the dreaded second sock syndrome, so thought I would not knit two socks the same. I either put two socks together of the same colour combos but used differently or a different pattern from the range using the same yarn colours. You can find out a bit more on my No second sock syndrome group. Happy Knitting.
