Socks knit on tiny needles are not always the rule. Heavier yarns and larger needles knit up great socks for boots and clogs and are great for wearing year round. There are easy sock patterns that have just enough definition to make your first socks or your umpteenth pair a real joy.
"So simple silk garden" is a free pattern for using 6-ply, sport, or dk yarn, in small, medium and large sizes that knitnscribble has used over and over again for heavier socks.
The single cable on opposite sides of the socks gives plenty of definition, which provides very small, if any, challenge to the beginner sock knitter, and at the same time, lends interest to this easy sock pattern. The pattern calls for US 3 - 6 needles, depending on what size and texture you seek; a US 4 (3.5 mm) needle works well.
Where to buy 6-ply sock yarn? Always best to purchase sock yarn that has a little nylon in the blend or superwash merino, so the socks will last a while with heavy wear. Superwash designation means that the yarn has an extra twist, will stand up to boot or clog wear, and doesn't need the extra nylon. I always knit the heel and toe with a strand of polyester thread combined with the yarn to strengthen the socks.
Regia 6-ply yarn, dk or sport weight. Zauberball Starke 6 by Schoppel Wolle is a great choice at 437 yds/150g.
