Free Pattern Friday – Onyx Mitts
There is something deeply satisfying about a knitting pattern that looks far more complicated than it actually is. The Onyx Mitts are exactly that kind of project — the sort of thing you can hold up at your knitting circle and watch people’s eyes go wide, even though your hands barely broke a sweat putting them together. If you have been looking for a free fingerless mitt pattern that combines texture, elegance, and wearability in a single tidy package, welcome to your new favorite Friday.
Pull up a chair, get your coffee, and let’s talk about everything you need to know to cast on your first pair of Onyx Mitts today.
What Are the Onyx Mitts?
The Onyx Mitts are a pair of fingerless gloves worked in a deeply textured stitch pattern that gives the fabric a rich, almost dimensional quality — think of the way light catches a polished piece of black gemstone, with facets and depth appearing depending on the angle. The name is not accidental. Whether you knit them in a true jet black or in any other color that strikes your fancy, the stitch pattern creates that same shifting, luminous surface.
These mitts are worked flat or in the round (the pattern below offers both options), feature a simple thumb gusset that fits a wide range of hand shapes, and use a stitch repeat that is easy to memorize after just one or two pattern rows. They are the kind of project that travels well — no complicated charts to lose on the train, no beads or wire or seventeen colors to manage. Just you, your yarn, your needles, and a rhythm that clicks into place almost immediately.
Who Is This Pattern For?
The Onyx Mitts are written for knitters who are comfortable with knit and purl stitches and who have made at least one or two projects in the round. You do not need to know anything fancy. If you can work a 2×2 rib, read a basic stitch pattern, and pick up stitches for a thumb, you are more than ready.
That said, these mitts are also genuinely enjoyable for more experienced knitters. The stitch pattern has just enough going on to keep your attention — you are not mindlessly knitting stockinette for hours — but it is absolutely relaxed enough that you can follow along with a podcast, a film, or a long conversation without losing your place. Think of it as the sweet spot between “too easy to stay interesting” and “too hard to be relaxing.”
Materials You Will Need
Before you dive in, gather your supplies. Here is what the pattern calls for:
Yarn: Approximately 200–250 yards of a fingering weight yarn (also called sock weight or 4-ply). The stitch pattern really sings in a yarn with good stitch definition — a tightly plied wool, a wool-nylon blend, or a smooth merino will all show off the texture beautifully. If you want that true onyx drama, try a deep charcoal or true black. But the pattern also looks stunning in jewel tones like sapphire, forest green, or burgundy, and surprisingly lovely in soft neutrals too.
Needles: US size 1 (2.25 mm) or US size 1.5 (2.5 mm) double-pointed needles, or your preferred method for small circumference knitting (magic loop, two circulars, or a short circular all work fine). Check your gauge and adjust accordingly.
Notions: A stitch marker or two, a tapestry needle for weaving in ends, scissors, and a small amount of waste yarn or a stitch holder for the thumb stitches.
Gauge: Approximately 32 stitches and 44 rows over 4 inches (10 cm) in stockinette stitch, after blocking. Gauge is not critical for these mitts the way it would be for a fitted sweater, but you want your fabric to be dense enough to have body without being so tight it feels stiff.
Sizing: The pattern is written in two sizes — Small/Medium and Medium/Large. A finished hand circumference of approximately 7 inches (S/M) or 8 inches (M/L).
The Stitch Pattern: A Closer Look
The texture on the Onyx Mitts comes from a simple but beautifully effective combination of twisted stitches and purls arranged in a repeating grid. The result is a surface that looks almost woven — rows of small, firm knot-like stitches separated by shallow channels of purl, giving the whole fabric a structured, architectural quality.
The stitch pattern is worked over a multiple of 4 stitches and takes just 4 rows to complete. Once you have worked through the repeat once, you will find it is the kind of thing your hands start to remember on their own. By the second mitt, you will likely not need to look at the instructions at all.
Here is the stitch repeat:
Row/Round 1: (K1 tbl, p1) repeat to end.
Row/Round 2: (P1, k1 tbl) repeat to end.
Row/Round 3: Repeat Row/Round 1.
Row/Round 4: Repeat Row/Round 2.
The “tbl” stands for “through the back loop,” and it is this small twist that gives the knit stitches their firm, gem-like quality. Working through the back loop crosses the stitch slightly, creating a denser, more defined stitch that catches the light differently than a standard knit and gives the fabric its characteristic texture.
The Free Pattern

Abbreviations:
- CO: Cast on
- K: Knit
- K1 tbl: Knit 1 through back loop
- P: Purl
- PM: Place marker
- SM: Slip marker
- M1L: Make 1 Left (left-leaning increase)
- M1R: Make 1 Right (right-leaning increase)
- BO: Bind off
- Rep: Repeat
- St(s): Stitch(es)
- RS: Right side
- WS: Wrong side
Cast On
Using your preferred cast-on method, CO 56 (64) sts. Join to work in the round, being careful not to twist. Place a marker for the beginning of the round.
If you prefer to work flat, CO 57 (65) sts and work back and forth, seaming at the end. The instructions below are written for working in the round; notes for flat knitting are included in brackets where the method differs.
Cuff
Work the following rib for 1.5 inches (approximately 16–18 rounds):
(K2, P2) to end of round.
Hand
Begin the Onyx stitch pattern:
Round 1: (K1 tbl, p1) to end.
Round 2: (P1, k1 tbl) to end.
Round 3: Repeat Round 1.
Round 4: Repeat Round 2.
Work Rounds 1–4 a total of 3 times (12 rounds of texture pattern).
Thumb Gusset
On the next round, you will begin increasing for the thumb gusset. The gusset sts are worked in stockinette (plain knit) to keep the shaping clean and easy to follow.
Set-up Round: Work 28 (32) sts in pattern, PM, k1, PM, work to end in pattern.
Gusset Round 1 (increase round): Work to first marker in pattern, SM, M1L, k to second marker, M1R, SM, work to end in pattern. (2 sts increased)
Gusset Round 2: Work to first marker in pattern, SM, k to second marker, SM, work to end in pattern.
Repeat these 2 rounds until you have 15 (17) sts between the gusset markers — approximately 7 (8) increase rounds completed, with 13 (15) total gusset rounds worked.
Thumb Separation
Next round: Work to first marker in pattern, remove marker, place the 15 (17) gusset sts on a holder or length of waste yarn, remove second marker, CO 3 sts using backward loop cast-on, work to end in pattern.
You will now have 58 (66) sts on the needles. Continue working in the Onyx stitch pattern until the hand measures approximately 1 inch past the thumb separation, or to your desired length (most people prefer to end at about the base of the fingers, but you can work a bit longer for extra warmth and coverage).
Upper Hand Finishing
Work 6 rounds of (k2, p2) rib for a neat, tidy edge at the top.
BO loosely in rib pattern. An Italian bind-off or a stretchy sewn bind-off works beautifully here if you want extra give.
Thumb
Return the held 15 (17) sts to your needles. Pick up and knit 3 sts from the CO sts at the thumb gap. Join to work in the round — you will have 18 (20) sts.
Work in (k1, p1) rib for 8 rounds, or until the thumb is as long as you like.
BO loosely in rib.
Finishing
Weave in all ends. Block gently by soaking in cool water, pressing out excess moisture in a towel, and laying flat to dry. You will be amazed at how much the texture blooms and evens out after even a brief blocking.
Work the second mitt to match.
Tips for Getting the Best Results
On yarn choice: A smooth, tightly spun yarn is your best friend with this pattern. Fuzzy or halo yarns like mohair or angora will blur the stitch definition and lose the whole point of the texture. Save those for a different project. For the Onyx Mitts, you want something sleek and precise.
On needle type: Metal needles tend to work well here because they let the stitches slide easily — important when you are working that slight twist on every knit stitch. Wood or bamboo needles are lovely too if you prefer a little grip, but they can slow you down slightly on the tbl stitches.
On gauge tension: Some knitters tighten up when working stitches through the back loop. If you find your fabric is pulling or puckering, try going up half a needle size. The fabric should feel dense but not rigid.
On making a match: Knitters often find the second mitt in a pair knits up faster than the first, but it can still drift slightly in tension or gauge if you pick it up weeks later. If you are prone to this (as many of us are), consider casting on both mitts at the same time using two separate balls of yarn. It takes a moment to set up, but it guarantees a matched pair.
On color choices: While black is the obvious and spectacular choice for these mitts, do not sleep on other options. A deep teal or petrol blue makes the texture look like moving water. A warm terracotta or rust gives the mitts a completely different, earthy personality. A soft grey or oat looks quietly sophisticated and goes with absolutely everything. The pattern is versatile enough to reinvent itself completely depending on what you put into it.
Variations and Ideas
Once you have made one pair and fallen in love with the stitch pattern, here are a few ways to play:
Longer mitts: Simply work more repeats of the texture pattern before beginning the thumb gusset. Three or four extra repeats will give you a wrist-covering length; six or eight will take you almost to elbow length if you want something truly dramatic.
Gloves: This pattern translates beautifully to a full glove. Work the hand as written, then instead of a single top rib, work individual fingers using your preferred method. The texture pattern on the fingers is a bit fiddly at small circumferences, so many knitters simply switch to stockinette or 1×1 rib for the fingers and save the Onyx pattern for the hand and wrist.
Cowl: If you love the Onyx stitch pattern and want to see it at a larger scale, try using it as the main texture on a simple cowl or hat. Cast on enough stitches for your circumference, work the stitch repeat, and see how different it looks at a larger gauge in a bulkier yarn. It becomes almost architectural — more geometric, bolder in scale.
Colorwork trim: A few rounds of a contrasting color at the cuff or the top edge of the mitt (worked in a simple stripe or a tiny colorwork border) can be a beautiful addition without requiring any additional complexity in the main body of the pattern.
Why Fingerless Mitts Are Worth Your Time
If you have never made a pair of fingerless mitts before, or if it has been a while and you are thinking about what to cast on next, let me make the case.
Fingerless mitts are genuinely one of the most practical knitted items you can make. They provide warmth exactly where you need it — the back of the hand, the wrist, the palm — while leaving the fingers free for typing, phone scrolling, coffee cup holding, and all the other things modern life requires. They are season-extending in a way that full gloves are not: mild enough to wear on a cool autumn morning, substantial enough to make a real difference on a cold winter commute.
They are also incredibly giftable. A pair of well-made, thoughtfully crafted fingerless mitts in a color the recipient loves feels personal and special in a way that a purchased gift rarely matches. They are small enough to complete in a reasonable timeframe — even a dedicated beginner can finish a pair in a week or two — but substantial enough to feel like a real handmade gift.
And from a purely selfish knitting perspective, they are one of the best value projects for the time you put in. A few evenings of pleasant, rhythmic knitting, and you have something beautiful to wear every day for years.
A Few Last Words Before You Cast On
The Onyx Mitts have become a personal favorite in rotation of go-to projects exactly because they hit that rare balance: interesting enough to make the knitting engaging, simple enough to make it relaxing, and beautiful enough at the end that you feel genuinely proud of what your hands made.
Whether you are making these for yourself, for someone you love, or just because you saw the stitch pattern and needed to try it immediately (completely valid), I hope you enjoy every round. Block them well, wear them often, and if you make a pair, I would absolutely love to see them.
Happy knitting, and happy Free Pattern Friday.
