I’m just a simple Swiftie, but even if you aren’t, these mitts are easy to make with or without the additional duplicate stitch lettering and bead “ring”. I have made the plain version many times, which only needs some ribbing and stockinette in the round done with 50g of fingering weight yarn.
The mitts are a simple knit in your favorite fingering weight yarn (I used my own hand dyed Happy Habit cashmere merino blend). I added the charted lettering in duplicate stitch with sparkle orange yarn and sewed a few beads over my left ring finger. You could adapt for stranded knitting, but I didn’t because I didn’t want to catch my fingers on the floats when putting the mitts on. I have kits with both yarns and beads in my store.

Finished size laying flat for each mitt: 9.5” long by 3.75” across
