This is a vintage pattern.

Yarn is described as “three thread”. Pattern says “1 lb yarn makes 3 pairs of socks.” Jaggerspun 3/8 yarn is the best modern equivalent.

No gauge is given. Calls for size 13 needles. These are equivalent to a modern US size 1 needle (metric size 2.25 mm).

Four versions of the same pattern are on the site:

• one in the original 19th century terms (this pattern)
• a modern interpretation for experienced sock knitters
• an intermediate version of the same pattern with more explanation of terms and techniques, and
• a beginner’s version in worsted weight yarn. This is not a period pattern as there is no evidence that socks were ever knit in worsted weight in the 19th century.
