This fall we're showing two new Bulky yarns. Unfortunately, both 'Bulky' and 'Chunky' can seem like subjective terms. I thought I would write a little about our new yarns, Burley Spun, and Grande to explain how chunky chunky is.
The Craft Yarn Council tops out their Weight System with their 5th and 6th categories; Bulky and Super Bulky.
The Bulky category comes after Medium (worsted and aran yarns) and includes Chunky, Craft, and Rug Yarns. Their gauges over 4" of stockinette stitch should work out to 12-15 stitches. For most knitters these yarns require needles from 5.5mm to 8mm. Crocheters are advised to use a 6.5mm to a 9mm hook.
Super Bulky is the heaviest category and comes after Bulky. This whimsical title is applied to Roving, but also to Bulky yarn. ?!?!?! Confusing or what? Best to focus on gauges. The CYC describes Super Bulky as having a gauge of 6-11 stitches (in 4" worked in stockinette stitch). These yarns should be worked with needles larger than 8mm (15mm is the biggest needle in most shops. The Loop carries these sizes and does get in circular Addi needles in sizes over 15mm. We can always special order these for you!) Crocheters should use a hook size greater than a 9mm. I would advise using the biggest hook you feel comfortable with.
PS Can you guess what our inventory code for "Brown Seep Burley Spun" is? Yeah, it's double BS. Totally.
