Thrums are a way to add warmth and bulk to a knitted item by knitting little bits of wool roving into the work. This video demonstrates the technique on it’s own, and next week we have a tutorial on thrummed mittens. Many thanks to Knitter’s Pride and their Marblz needles, for sponsoring this video.
The Knitter’s Pride tools I use in this video are Marblz circular needles from an interchangeable set that includes nine needle sizes.
Q: Can I add thrums to any knitted item?
A: Yes, and no. Because thrums add bulk, the knitted item has to be larger to accommodate the thrum stitches. This can throw off the proportions of a pattern. For example, you can make thrummed slippers, knitting a larger size than you would knit if you were not adding thrum stitches. This would create a pair of slippers that would fit well in width, but would likely throw off the proportions for the length of the slipper. My recommendation is to knit a pattern specifically designed for thrums, until you are familiar with the technique and the adjustments you’ll need to make to patterns. (I have a thrummed mittens pattern coming out next week, or you can search Ravelry for thrummed patterns.)
Q: Can I use a fiber other than wool, like superwash wool or a synthetic for thrummed knits?
A: Your best bet is to stick with 100% non-superwash wool for thrummed knits for the best warmth and wear-ability. As the item is worn, you want the thrums to felt to themselves and the knit fabric to create a layer of smooth insulation.
