🧤 What Are Thrummed Mittens?
Thrummed mittens originated in Newfoundland and Labrador, Canada — a region famous for brutal winters and cozy knitwear. Instead of regular insulation, thrummed mittens use small tufts of unspun roving (“thrums”) that are knitted into the fabric.
Those fluffy thrums create a soft, felted interior that keeps your hands warm even on the coldest days. Once you wear them, there’s no going back to plain mittens!

NOTES
⭐️ Directions are for the smallest size; changes for all other sizes are in parentheses. When only one number is given then that number applies to all sizes.
⭐️ A thrum is a lock of fleece about 4″ [10 cm] long with both ends folded to the middle, then twisted/rubbed together. Center of thrum should be approximately the same thickness as the yarn being used for the mitten.
⭐️ The end of the thrums (I call them the butterfly) will tuck into the wrong side of the mitten.
⭐️ Prepare thrums prior to beginning the mitten.
⭐️ Mittens are worked entirely in the round from cuff to tops of fingers.
⭐️ Thrums are arranged in a polka-dot pattern; every 6th stitch, and every 4th round.
⭐️ If the thrum is getting sucked in on one side after the knit together through the back leg, just use your needle to pull the sucked in section out (I show how to do this in the video).
