Here's my modern take on the classic argyle pattern — featured in the current issue of Vogue Knitting. The pattern is graded for the widest range of sizes. But, grab your needles and a crochet hook because it is knitted, then the black diamonds are added in crochet. I designed it for Cardiff's light weight, luxurious Cashmere Classic.
And FYI: Argyle derives from the tartan of Clan Campbell of Argyll in western Scotland, and has been used for kilts, plaids, and the patterned socks worn by Scottish Highlanders since the 17th century. Argyll was an ancient kingdom in Great Britain, a medieval bishopric, as well as an early modern earldom and dukedom. Perhaps having Great Britain in my family heritage is what inspired me to create this design. Cheers — James
