Yarn Weight Differences

One of my biggest pet peeves is the way the term “worsted weight” or “medium weight” or “#4 weight,” all of which are supposed to be the same, are not always the same.

This supposedly universal weight description differs according to several factors.

It differs with the brand. Worsted weight in one brand is often much different than worsted weight in another brand.

It differs with the color - differently colored dyes affect the texture and thickness of the yarn to a noticeable extent.

And, it differs with the type of yarn - yarn with metallic threads running through might be heavier; yarns of a “boucle” texture might be lighter in weight.

I just finished four pieces for a poncho. Two pieces are Red Heart; one is Caron; and the other brand name eludes me but it has metallic thread running through it. Luckly, the first three came out all the same. The one with the metallic thread will need another two rows or so, in order to be the same size and its partners. This also means that when I’m joining, I might have to pin this piece and measure so that it comes out right.

The thing to remember is to always measure and to always work to gauge, whether the pattern’s gauge, or the gauge you prefer. Just remember to check it when using more than one kind or color of yarn.
