Thrums / Thrumming

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 Knitterā€™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?
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?
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.

Instructions for the swatch I used for demonstration in the video:
CO 40 stitches
Bottom Border: Knit 8 rows, purl 1 row
Row 1 (RS): Knit 8, work a thrum stitch, (knit 3, thrum) 6 times, knit 7
Row 2: Knit 5, purl 30, knit 5
Row 3: Knit all stitches
Row 4: Knit 5, purl 30, knit 5
Row 5: Knit 6, work a thrum stitch, (knit 3, thrum) 7 times, knit 5
Row 6: Knit 5, purl 30, knit 5
Row 7: Knit all stitches
Row 8: Knit 5, purl 30, knit 5

Information on things you’ll see in this video:
The long-staple roving I used is from Knit Picks.
The shorter-staple roving I used is from Colorways Gallery.

The green yarn I used for demonstration is Knit Picks Wool of the Andes Bulky.

The nail polish I’m wearing is by Julep, color “Ilga”.

My silver ring is actually a knitting needle gauge, and can be found here.

  1. What a FUN technique! Would LOVE to see you do a video on slippers (with our without this process). Thanks for another great video!
