One thing is for sure, my feet are going to be toasty this winter! For this project, I used Patons Kroy Socks in Coal for the main color and Patons Kroy Socks in Mexicala Stripes for the contrast color. Even though these socks took a little time to make, they were well worth the extra effort. I followed the pattern exactly and I will admit, they are a little big. This can easily be adjusted since they are big foot-length-wise. The pattern calls for 2 balls of Coal and I actually ended up using 2.3 balls. As for the Mexicala Stripes, I only used 1.7 balls. I also recommend recreating the pattern chart. I used a spreadsheet program to make mine. However, you can definitely do this the old-fashioned way with a pencil and a sheet of graph paper. Overall I love these socks and cannot wait for it to get cold enough outside to wear them. Which, here in Austin, TX, happens around mid-January when we dip down into the 40's for a week or two.
