I made a pair of socks with some of the leftover yarn. For the cardigan the yarn was held double, single for the socks. https://ravel.me/JConklin/css

08.09.2018 - Chartreuse yarn arrived today and it’s lovely - excellent quality and dyeing. I’ve decided to order the purple speckled yarn from Long Dog as well.
The dates of purchase for the natural and Copper Corgi yarns are approximate - to the best of my memory. Yarns are all held double. Making the standard version.

07.14.2018 - I don’t have the purple contrasting colors yet. The green/chartreuse yarn has been ordered. I’m going to choose the same approximate colors as the ones shown in the pattern. This is one of the reasons that I was drawn to the pattern.
