For projects that knit up at a nice clip in plump and satisfying yarns, explore our collection of mostly free aran- and worsted-weight yarn knitting patterns. With a gauge of about 4-5 stitches per inch, worsted weight yarn is on the thinner side of the range and aran on the thicker… Both are utterly classic! Cast on for warm sweaters, cozy scarves and blankets, winter hats and mittens, and more, in yarns like our soft, smooth, and supple extra fine merino Plenty and our earthy alpaca-highland wool Yonder.
