The Arkose Crochet Duster Cardigan pattern is the layer you reach for when you want the drama of a long cardigan without the weight of a jacket. It has a relaxed, open-front fit, tapered sleeves, and just enough texture to keep the fabric interesting while still letting that beautiful drape do most of the talking.

Although this duster cardigan crochet pattern uses worsted weight yarn, the larger hook and tall stitch pattern create a fabric that feels light, soft, and wonderfully fluid. I made mine in 100% cotton, so it is breathable enough for transitional weather but still cozy when the temperature starts making questionable decisions.

The pattern is written in nine sizes from XS through 5XL, and the length, sleeves, and body width can all be adjusted for the fit you want. Wear it over jeans and a tank, leggings and boots, or a dress when you want to look pulled together with suspiciously little effort.

The cardigan is named Arkose after a sandstone with coloring similar to the rose-taupe yarn I used. You can stay in that warm, earthy world or choose a color that feels completely your own.

Why You’ll Love This Crochet Duster Cardigan

• The long, open-front shape instantly makes a simple outfit feel intentional.
• A larger hook gives worsted weight yarn a lighter, more fluid drape.
• The crossed treble crochet sections add texture without making the entire project complicated.
• Tapered sleeves keep the oversized silhouette from feeling bulky.
• The pattern includes nine sizes from XS through 5XL.
• You can adjust the body length, sleeve length, and width to suit your proportions and preferred fit.
• The new video tutorial lets you see the construction and trickier stitch sections in action.

How the Arkose Duster Cardigan Is Constructed

The cardigan begins as one large piece worked in turning rows from the lower back upward. After the lower body reaches the required length, the work is divided into three sections: one back panel and two front panels. The panels are continued separately and then seamed across the shoulders to create the arm openings and open front.

Next, a ribbed border is worked along one front edge, around the back of the neck, and down the opposite front edge. The sleeves are crocheted directly onto the arm openings in turning rounds, gradually tapered, and finished with ribbed cuffs.

In other words: no collection of mysterious garment pieces waiting around for you to remember how they fit together. The main body stays connected, and the finishing steps give it its final cardigan shape.

Materials You Will Need For This Crochet Duster Cardigan Pattern

Choosing Yarn for the Best Drape

I used 100% Pima cotton in a worsted weight for the original cardigan. Cotton gives the finished fabric softness, breathability, and enough weight to help the long silhouette hang beautifully.

You may substitute another worsted weight yarn, but make a gauge swatch before committing to cardigan quantities. Fiber content matters here: a springy wool or acrylic can create a warmer, loftier cardigan, while cotton, bamboo, or a soft plant-fiber blend will generally give you more fluid drape.

The goal is not simply to find another yarn with a number 4 on the label. You want a yarn that meets gauge and creates a fabric you would actually enjoy wearing. Swatching is not the most thrilling part of a cardigan, but neither is discovering at the shoulder seam that you have crocheted a tasteful area rug.

FAQ & Terms

Gauge:

4″x4″ = 13 stitches x 5 rows of double crochet.

I encourage you to make a small rectangle swatch before you jump into this crochet duster cardigan pattern to be sure your gauge is correct. It’s also a good idea to measure now and again and try it on as you go along. This will ensure your duster will fit right when it’s done! This cardigan has a lot of drape and flexibility so gauge is a general guideline.

Sizing:

This pattern is written in size XS with sizes S, M, L, XL, 2XL, 3XL, 4XL & 5XL following in parenthesis like this: XS(S, M, L, XL)(2XL, 3XL, 4XL, 5XL). The size can be easily modified by taking your measurements and adjusting the number of stitches or rows. The model pictured is wearing size XS with height 5’4 and a bust of 33″.

TIP: The written pattern also includes a detail sizing grid with measurements in inches and the number of rows and stitches for each size. Using the sizing grid compared to your measurements will allow you to easily customize the cardigan to your exact measurements.

Length Measurement:

XS: 42″
S: 43.2″
M: 45″
L: 46.5″
XL: 48″
2XL: 49.5″
3XL: 51″
4XL: 52.5″
5XL: 54″

Bust Measurement: the bust measurements here are based on the cardigan laying flat and closed. Just remember when you wear it, it will add several inches across the front because it will be worn open (as pictured). So, don’t let these measurements throw you off because they will definitely “look” too tight.

XS: 32″
S: 34″
M: 36″
L: 38″
XL: 40″
2XL: 42″
3XL: 44″
4XL: 46″
5XL: 48″

Fit and Customization Notes

The Arkose is designed to be worn open, so the finished bust measurements may look smaller than expected when you compare them with your full bust measurement. Once worn, the open fronts add coverage across the body without meeting at the center.

Use the sizing information in the pattern together with your own measurements, and try the cardigan on as you work whenever possible.

To adjust the length: Add or remove double crochet rows before dividing the body into the back and front panels. Add the same adjustment to the panel rows so the front and back remain even.

To adjust the sleeve length: Try the cardigan on as you approach the cuff. Add or remove the indicated repeat rows before beginning the ribbed cuff.

To adjust the overall width: Choose the size whose finished measurement and amount of front coverage best match your preferred fit. Any stitch-count customization should preserve the pattern repeats used in the textured sections.

The Written Pattern

Main Body:

NOTES:

• The main body is worked in rows, turning at the end of each row – the number of turning chains will be specified per row and will vary from 2-4
• The turning chain never counts as a stitch
• Wrong side (ws) will be indicated so you can keep track of the outside and inside of the cardi

Row 1 (ws): fdc 96(102, 108, 114, 120)(126, 132, 138, 144), ch 2, turn

Row 2 (rs): (fpdc in next st, bpdc in next st) x across, ch 2, turn

Row 3: (fpdc in next st, bpdc in next st) x across, ch 2, turn

Row 4-7: dc across, ch 2, turn

Row 8: sk next st, tr in next st, tr in last skipped st, (sk next st, tr in next st, tr in last sk st) x across, ch 1, turn PHOTO 03-05 shows how to complete the “V” stitch you’re accomplishing during this row. PHOTO 01 & 02 shows middle of row 8 close-up

Row 9: hdc across, ch 2, turn

Row 10-15: repeat rows 8-9 (ending with the hdc row)

Row 16-19: repeat rows 4-7

Row 20-27: repeat rows 8-15

Row 28-31: repeat rows 4-7

Row 32-39: rep rows 8-15, ch 2, turn

At this point, the rest of the body of the cardigan is worked using dc rows. Soon, you will divide the rectangle into 3 sections – 1 for the back and 2 for the front panels. You can easily adjust the length of the cardigan by adding dc rows before you do the dividing as just described.

Row 40-43(45, 46, 48, 49)(51, 52, 54, 55): dc in each st across, ch 2, turn

Divide work into 3 sections for back & front panels: The back will have 54(58, 60, 64, 66)(70, 72, 76, 78) st, each side panel will have 21(22, 24, 25, 27)(28, 30, 31, 33) st PHOTO 06

Panels:

NOTES:

• You will now be working on the 3 panels as divided above
• You will be working turning rows of dc
• Chain 2 and turn at the end of every row – the turning doesn’t count as a stitch
• If you want the cardigan longer, continue to add dc rows to the panels until you find your perfect length

FRONT RIGHT PANEL:

Row 44-53(46-55, 47-57, 49-59, 50-61)(52-63, 53-65, 55-67, 56-69): dc in each st across, ch 2, turn [21](22, 24, 25, 27)(28, 30, 31, 33)

Fasten off. PHOTO 07

BACK PANEL:

Rejoin yarn with a sl st in the next st marker for the back panel and ch 2. When you make your first dc of row 44, remember to dc in the st where you just rejoined the yarn with a sl st.

Row 44-53(46-55, 47-57, 49-59, 50-61)(52-63, 53-65, 55-67, 56-69): dc in each st across, ch 2, turn [54](58, 60, 64, 66)(70, 72, 76, 78)

Fasten off.

FRONT LEFT PANEL:

Rejoin yarn with a sl st in the next st marker for the front left panel and ch 2. When you make your first dc of row 44, remember to dc in the st where you just rejoined the yarn with a sl st.

Row 44-53(46-55, 47-57, 49-59, 50-61)(52-63, 53-65, 55-67, 56-69): dc in each st across, ch 2, turn [21](22, 24, 25, 27)(28, 30, 31, 33)

ASSEMBLY OF THE MAIN BODY RECTANGLE:

• Choose the side you want facing out, they will be very similar and it’s just up to you which side you like the look of better! But don’t stress about it, it’ll look great either way!
• Lay the piece flat and fold the front panels inward to lay on top of the back panel, with the right side facing out.
• Using a length of yarn and a tapestry needle, seam across the shoulders from the outside corner into the center using the whip stitch.
• Fasten off and weave in all ends. PHOTO 08

Ribbed border / collar:

With right side facing out, rejoin yarn at the front bottom corner (right or left, depending on if you’re right-handed or left-handed) and ch 2. PHOTO 09

Row 1: dc up the front edge, around the neck, and back down the opposite front edge – placing 1 dc at the end of each of the hdc rows, 2 dc in the end of the dc rows and 3 dc in the end of the tr rows, ch 2, turn

Row 2: (fpdc in next st, bpdc in next st) x around to the start of the other front edge where you began, ch 2, turn

Row 3: (fpdc in next st, bpdc in next st) x around to the start of the other opposite front edge

Fasten off and weave in end.

Sleeves:

NOTES:

• The sleeves are crocheted directly onto the cardigan.
• The sleeves are made using turning rounds, slip stitching, chaining 2, and turning after each round unless otherwise specified.
• The sleeves should have 40(40, 44, 44, 48)(48, 52, 52, 56) stitches around based on the sleeve opening.
• Check the length of your sleeves as you near the end and add or subtract rows to achieve your desired length.

Rejoin yarn at sleeve opening in the armpit using a sl st and ch 2 (doesn’t count as a st).

Rnd 1: dc in each st around the arm opening, placing 2 dc in the end of each row [40](40, 44, 44, 48)(48, 52, 52, 56)

Rnd 2-3(4, 6, 7, 8)(8, 9, 9, 10): dc in each st around, ch 2, turn [40](40, 44, 44, 48)(48, 52, 52, 56)
