This is a test pattern I completed. As of the time of writing this post, the pattern is not yet available. Until then, check out the designer's page here.
I used a sport weight (3) yarn and a size G hook (4.0 mm.) For the MC, I used 6.56 oz or about 663 yds. For the CC, I used 1.58 oz or about 140 yds. The amounts were calculated based upon the labels on the skeins.
The skirt is about 27.5” in length.
