Why You'll Love This Colorblock Oversized Cardigan Pattern

I absolutely love this pattern because it turns simple stitches into a bold, colorful statement piece that everyone can personalize. I enjoy how the panel construction makes it easy to change colors and add unique block layouts for each project. The mattress stitch assembly gives a neat, professional finish that I find very satisfying to complete. Making this cardigan feels like a thoughtful gift β€” I always imagine someone cozying up in it and smiling.

Switch Things Up

I love customizing this cardigan by switching up color layouts; try vertically split panels or a gradient of three shades for a different mood.

If you want a smaller version, I change hook size and yarn weight β€” use a DK yarn with a 4.0mm hook for a neater, smaller cardigan.

For chunkier, cozier results I pick bulky yarn and a 6.5mm hook, which makes the cardigan more like a chunky coat that I adore for cold weather.

I often change sleeve length to three-quarter or full length depending on seasonal wear; simply repeat or remove rows in the sleeve body to adjust length.

Try a ribbed hem by working additional BLOhdc rows at the bottom edge to add stretch and texture to the cardigan.

Embellish with appliques or embroidered motifs on panels for a personalized touch that makes each piece truly unique.

Swap the button band for an open-front shawl collar by adding more rows and shaping the front panels for a different silhouette.

I sometimes add pockets by crocheting small rectangles and sewing them to the front panels for functionality and style.

For a fitted look instead of oversized, reduce the number of chains in the front and back panels evenly and check fit as you go.

Play with stitch patterns: replace some hdc rows with alternating dc rows or a simple V-stitch for a lacy texture while keeping the same panel dimensions.

Common Mistakes & How to Fix Them

βœ— Not checking gauge before starting can lead to a poor fit; make a 5"x5" gauge swatch (17 hdc x 12 rows) and adjust hook size accordingly. βœ— Skipping stitch markers when working the upper panel decreases causes confusion; place a stitch marker on your hdc2tog and on rows you need to count for accurate shaping. βœ— Changing colors without securing tails properly results in loose ends and messy joins; weave in ends or secure with a slip knot and weave later with a tapestry needle. βœ— Not leaving long enough tails for sewing the panels will make assembly difficult; leave tails 3x-4x the length of the panel edge depending on use and size of panel. βœ— Pulling yarn too tight while doing the mattress stitch makes seams pucker; insert the needle to catch outermost posts and pull gently to make invisible, even joins.

β€” Back Panel :

Info :

For the back panel, you can design it in two ways: 1) Horizontal layers of different colors – simple and perfect for beginners or for those who want minimal sewing. 2) Colorblock pattern – requires sewing using the mattress stitch or any other stitch you are comfortable with.

Design 1 - Step 1 :

Using your color of choice: Chain 76 (84, 92, 100, 108, 116). Hdc on the 3rd chain from the hook. Hdc on each of the next sts until you reach the end of the row.

Design 1 - Step 2 :

Ch 2. Flip your work then hdc on the same st. Hdc on each of the next sts until you reach the end of the row.

Design 1 - Step 3 :

Repeat Step 2 until you reach your desired length for that color. Cut the yarn and fasten off.

Design 1 - Step 4 :

To start with your new color, create a slip knot with your new yarn color, sl st on the st where you ended.

Design 1 - Step 5 :

Ch2. Flip your work then hdc on the same st. Hdc on each of the next sts until you reach the end of the row.

Design 1 - Step 6 :

Repeat Step 5 until you reach your desired length for that color. Ch1, cut the yarn and fasten off. Do as many color changes as you want by repeating steps 4-6. Make sure that the total number of rows of the back panel match the total number of rows of your front panel.

Design 2 - Colorblock Pattern Step 1 :

Using your color of choice: Chain 39 (43, 47, 51, 55, 59). Hdc on the 3rd chain from the hook. Hdc on each of the next sts until you reach the end of the row.

Design 2 - Step 2 :

Ch 2. Flip your work then hdc on the same st. Hdc on each of the next sts until you reach the end of the row.

Design 2 - Step 3 :

Repeat Step 2 until you reach your desired length for that color. Cut the yarn and fasten off.

Design 2 - Step 4 :

To start with your new color, create a slip knot with your new yarn color, sl st on the st where you ended.

Design 2 - Step 5 :

Ch2. Flip your work then hdc on the same st. Hdc on each of the next sts until you reach the end of the row.

Design 2 - Step 6 :

Repeat Step 5 until you reach your desired length for that color. Ch1, cut the yarn and fasten off. You have now created the other half of your back panel. To create the remaining half, repeat steps 1-6 using your other color choices. Once you have created the two halves of your back panel, you have to connect them using the mattress stitch.

β€” Doing the Mattress Stitch :

Mattress Stitch - Info :

The mattress stitch is like tying your shoelaces, you work from side to side, inserting the laces from the bottom going up. Align the rows that you want to connect. Select the yarn color that you want to use. Work facing the correct side of the panels.

Mattress Stitch - Step 1 :

Cut a yarn with a length equal to 3x the length of your back panel.

Mattress Stitch - Step 2 :

Using your tapestry needle, insert the yarn through the first stitch on the right panel from the bottom going up. Leave enough end (1-2 inches) for weaving.

Mattress Stitch - Step 3 :

Then insert the yarn through the first stitch on the left panel from the bottom going up.

Mattress Stitch - Step 4 :

To secure your first stitch, insert the yarn once more through the first stitch on the right panel from the bottom going up. Then to the first stitch on the left from the bottom going up. You can make a single knot to make sure that the ends are secured. From this point forward, you will be working on the outermost post of each row. When inserting the needle, remember to always get at least 2 loops from the outermost post to make sure that the connection will be sturdy and secure.

Mattress Stitch - Step 5 :

Insert the needle to the outermost post of the opposite panel, from the bottom going up, do the same to the other panel. Do this until you reach the post on the last row. Make sure that the rows match while you are stitching them together.

Mattress Stitch - Step 6 :

To end the mattress stitch, insert the yarn through the first stitch on the right from the bottom going up. Insert the yarn through the first stitch on the left from the bottom going up. Repeat again to secure your last stitch. Make a single knot then fasten off. Tip: If you are having difficulties doing the mattress stitch, you can also try using sc or any other stitch that you are more comfortable with.

β€” Attaching the Panels and Sleeves :

Attaching front and back panels together - Info :

You will start by attaching the top portion of the front panel to the top portion of the back panel through the mattress stitch. Make sure that the rows match. Work facing the correct side of the panels.

Attaching front and back panels together - Step 1 :

Start sewing from the outer edge going to the middle part of the cardigan by doing steps 1-3 under the mattress stitch instructions. Work from the outer edge toward the center.

Attaching front and back panels together - Step 2 :

For the next stitches, continue stitching from side to side, inserting from the bottom going up, until you reach the last stitch in your front panel.

Attaching front and back panels together - Step 3 :

Make a single knot then fasten off. Do the same for the other side. You have now created the shoulder part of your cardigan.

Attaching the sleeve to the body - Info :

For this part, you will use mattress stitch to attach the sleeves to the front and back panel then down to attach the sides of the cardigan. Work facing the correct side.

Attaching the sleeve to the body - Step 1 :

Fold your sleeves in such a way that the seam will be positioned at the bottom (underarm area).

Attaching the sleeve to the body - Step 2 :

Using your stitch markers, mark the topmost portion of the sleeves, then mark the rows in your front and back panel where you want to attach the sleeves. Make sure the position in front is similar to back. e.g. put the stitch marker on the 20th row of the front panel and also on the 20th row of the back panel.

Attaching the sleeve to the body - Step 3 :

Attach the sleeves to the front panel first by doing the mattress stitch. You will work from the underarm area all the way up to the shoulders. Since you left a long tail for the sleeves, start the mattress stitch by inserting the needle to the outermost post of your marked row in the front panel. Continue doing the mattress stitch all the way up. Take note of the topmost stitch of the sleeve where you placed the stitch marker. This stitch should be connected to the topmost portion of the cardigan.

Assembly Instructions

  • Attach the two halves of the back panel using the mattress stitch, aligning rows and using a yarn length equal to 3x the back panel length for sewing.
  • Sew the top portion of each front panel to the top portion of the back panel from the outer edge to the middle using the mattress stitch, ensuring rows match and working facing the correct side.
  • Fold sleeve ribbing so seam is at underarm, mark topmost portion of sleeve and corresponding rows on panels, then attach sleeve to front and back panels by mattress stitch from underarm to shoulder.
  • After attaching shoulders and sleeves, sew side seams of the cardigan from underarm down using mattress stitch or preferred joining stitch, ensuring symmetrical placement and secure joins.

Important Notes

  • πŸ’‘Maintain consistent tension so that all panels and sleeves have the same width and row count for neat assembly.
  • πŸ’‘When changing colors, fasten off and start new color with a slip knot at the stitch where you ended to create clean color joins.
  • πŸ’‘Place stitch markers on hdc2tog positions and on rows to count for shaping the V and to align sleeves accurately during assembly.
