When it comes to knitting, familiarizing yourself with the various types of yarn can help you better plan for a project. There are many varieties of knitting wool yarn available, but they can be categorized into several weight groups to help simplify part of the process. A type of yarn that is not well known is double knitting weight yarn, or DK yarn.
DK is a little thinner than worsted. The terminology we don't use here is giving yarn weight in plies which is perplexing to us because plies are the number of individual strands that are twisted together to make up a acrylic yarn us and have no real impact on the thickness of the yarn, especially since many bulky yarns are actually single ply yarns just like cobweb yarn.
The deciding factor in the end has to be what the fabric looks like knit up in the gauge called for in the pattern. If the resulting fabric is pleasing to you, go ahead and use it. If it isn't, choose a different knitting wool yarn us or pattern, or, if you're up for it, modify the pattern to fit the yarn.
