I was so enamored of Knitty Gritty Thoughts' spiral cowl that I knit myself some matching mitts. I had exactly the same experience with the mitts that I had with the cowl: I thought I'd never wear fingerless gloves, that they would be impractical or not warm enough, and it turns out that I adore them and wear them and the cowl all the time!
I'm passing on the pattern to you. It's super easy and quick to knit. I had been knitting my cowl with two plies of Colourmart 4-ply weight cashmere (so a little lighter than fingering) held together, so I used them singly to knit these mitts. If you want to do something similar, you could use any luxurious fingering weight yarn to make the mitts, then hold it double to make a matching spiral cowl! I imagine that these would be lovely knit out of Malabrigo sock yarn, for example.
Spiral Mitts
Size: Ladies' small/medium ( 7" hand circumference) with 8 stitch/inch gauge; Ladies' large (8" hand circumference) with 7 stitch/inch gauge
Gauge: 8 stitches and 10 rows = 1 inch (small/medium); 7 stitches and 9 rows = 1 inch (large)
Note: these mitts are knit top-down (from the fingers to the cuff). This means that you start by knitting the thumb and hand parts separately. It also means that you can tailor it to the amount of yarn you have by knitting the cuff longer or shorter as needed.
First, make your thumb tube: CO 28 stitches and join to work in round, being careful not to twist. You can place a marker at the beginning of the round if you’d like. Work 4 rounds k1, p1, rib. Work in stockinette (all knit) until piece measures 1". Break yarn, leaving about a 2” tail, and place stitches on a piece of scrap yarn.
CO 56 stitches. Join to work in round, being careful not to twist. Work 5 rounds stockinette (knit). In next round, *k2tog, YO, rep. from * to end of round. Work 5 more rows stockinette. In next row, knit each stitch together with one loop from your cast-on to make a folded picot hem.
In next row, make one stitch (or increase by one stitch), then begin spiral eyelet pattern as follows: *k6, k2tog, YO, rep. from * to end of round. You should be able now just to spiral your way around the mitt ad infinitum. Work three full repeats of the spiral pattern (24 rounds), or until work measures 2” from folded-down hem.
In the next round, join your “thumb tube” to the mitts as follows: work 28 stitches in spiral eyelet pattern. Place a marker. Knit across all your live “thumb tube” stitches, working the first few stitches with working yarn and tail end of thumb stitches held together, and place another marker. Work remaining 29 stitches in spiral eyelet pattern.
In the next round, work to first marker in spiral eyelet pattern and slip marker. Slip-slip-knit (ssk) or work your favorite left-leaning decrease, knit to last 2 stitches before marker, k2tog, slip marker, and continue round in spiral eyelet pattern.
In the next round, work to first marker in spiral eyelet pattern, slip marker, knit to second marker, then finish round in spiral eyelet pattern.
Repeat the previous two rounds until there are two stitches between the markers. In the next round, work spiral eyelet pattern until one stitch before the first marker. Drop marker and k3tog, drop second marker and continue in spiral eyelet pattern.
Continue working in spiral eyelet pattern for 4 more full pattern repeats or until work measures 3” from bottom of thumb gore or 7” from folded-down hem. Work 6 rounds stockinette, decreasing by one stitch in the first row of stockinette. In the next round, *k2tog, YO, rep. from * to end of round. Work 5 more rounds stockinette. Break yarn, leaving a long tail. Fold hem and tack down live stitches with a tapestry needle to make picot cuff.
Weave in ends, block as you prefer and repeat with second mitt!
