About This The Cornflower Sweater Pattern

This pattern creates the Cornflower Sweater: an oversized pullover assembled from 8-inch floral motif granny-style squares. Each square is worked in rounds to form a flower center with chain-looped edges, finished with textured triple-crochet rows for a framed square.

Youll make multiple identical squares, block them for even shape, and sew them into two panels (front and back) to achieve a relaxed, drapey sweater. The design is customizable for size and length.

Why You'll Love This The Cornflower Sweater Pattern

I absolutely love this pattern because the floral squares feel both romantic and modern, combining lacy petals with bold framed edges. I enjoy how you can make each square quickly yet the assembly produces a beautiful statement piece. Sewing the squares together creates a lovely braided seam that looks professional and unique, and blocking really transforms the motifs. I also love that you can easily scale the sweater by adding or removing squares for a tailored fit.

Switch Things Up

I love how easy it is to customize this sweater by changing colors; try a gradient of blues for a tonal cornflower look or alternate contrasting colors for each square.

Want a smaller or larger sweater? Change yarn weight and hook size: bulky yarn with a larger hook makes a chunky, cozy version while lighter yarn creates a delicate, drapey sweater.

I often substitute the triple-crochet petal with double-treble or puff stitches for a different petal texture—experiment to see what you prefer.

Try adding a border of single crochet or ribbed rows around the neckline and hem for more structure and a finished look.

To make a cardigan instead of a pullover, leave a vertical seam open at the front when assembling and add button bands or a tie closure.

For more arm room, add an extra row of squares to the sleeves or the panel sides to increase the arm span and create a boxier silhouette.

I like to embellish finished sweaters with small crocheted flowers or embroidered centers on select squares for a personalized touch.

Consider lining the sweater with a lightweight fabric if you prefer less transparency—hand-sew a simple cotton lining to the inside panels before finishing seams.

To create a shorter crop version, remove the bottom row of squares and reconfigure the panel layout to maintain balance across the chest and shoulders.

I sometimes join squares as I go using a slip-stitch join for a flatter seam—experiment with running stitch vs slip-stitch joins to see which seam you like best.

Common Mistakes & How to Fix Them

✗ Skipping the slip stitch join at the end of a round can leave an uneven edge; always locate and sl st to the indicated chain stitch to close each round neatly. ✗ Not counting the chains at the beginning of rounds as stitches will give you the wrong stitch totals; remember chains at round starts count as stitches when checking your work. ✗ Failing to block your squares results in irregular sizes and mismatched seams; block each square to the specified measurement before sewing to ensure even assembly. ✗ Sewing squares without aligning wrong sides together can hide the braided seam effect; place wrong sides facing each other and use a running stitch to reveal the double-braided seam when unfolded.

Weight 4 yarn of choice (I used a cotton/nylon blend). 5mm – 6mm crochet hook. Yarn needle for sewing squares together. Blocking materials. Stitch markers, as needed.

— Square (make multiple) :

Round 1 :

Slip knot. Ch 6 and sl st to the first stitch.

Round 2 :

Ch 4, tc in the same st where you placed the sl st, ch 1. [All in the same stitch: tc, ch1, tc, ch1] x5. You should now count 12 tc st total, including the "ch 4". Find the "ch 4" you started this round with and sl st to the 3rd ch st.

Info :

*Note that chains at the beginnings of rounds count as stitches! Think of this "ch 4" as a "tc, ch 1".

Info :

Tc instructions: Yo twice, insert hook into stitch and pull up a loop. Yo and pull through the first 2 loops. You should have 3 loops. Yo and pull through the next 2 loops. You should have 2 loops now. Yo and pull through the remaining 2 loops.

Round 3 :

Each of the flower petals is essentially a tc 4 together, placed in the same stitch. The first petal will be a bit different from the others. Ch 2. Yo 2 times. Insert the hook under the next ch st of the round below. Pull up a loop. Yo and pull through the first 2 loops. You will have 3 loops left on your hook. Yo and pull through the next 2 loops. You should have 2 loops left on your hook.

Round 3, continued :

[Yo 2 times and insert the hook under the same ch st. Pull up a loop. Yo and pull through the first 2 loops. Yo and pull through the next 2 loops.] x2 You should now have 4 loops on your hook. Yo and pull through all 4 loops. Ch 4.

Round 3, continued :

[Yo 2 times and insert the hook under the next ch st of the row below. Pull up a loop. Yo and pull through the first 2 loops. Yo and pull through the next 2 loops.] x4. You should have 5 loops on your hook. Yo and pull through all 5 loops. Ch 4. Repeat the above "petal stitch" for every ch st you made in round 2. You should have 12 petals total. Sl st to the stitch at the top of the first petal.

Round 4 :

[Ch 7 sk 4 sl st] x12. Place your last sl st right before the first st of the round.

Round 5 :

Ch 7, sk 3, sl st (the sl st should be in the peak of that first chain loop). [Ch 7, sk 7, sl st] x2. Ch 4, sk 3, tc, ch 4, sk 3, sl st. <- Repeat this whole line a total of 3 times.

Round 5, continued :

[Ch 7, sk 7, sl st] x2. Ch 4. Find the first chain of this round and sl st to the 4th ch st.

Round 6 :

For this round, you will be placing one tc in each ch st. Ch 3, tc 3, ch1, sk1. [Tc 3, ch 1, sk1] x4. Tc 4, ch3, sk1.

Round 6, continued :

Tc 4, ch1, sk1. [Tc 3 ch 1 sk1] x4. Tc 4, ch3, sk1. <- Repeat this line a total of 3 times. Find the chain that started this round – sl st to the 3rd ch st. Tie off.

Info :

Repeat from the beginning to create several squares before moving on to assembly. Each square should measure about 8 inches wide. For best results, you will need to block your squares to even out the shape before assembly!

— Sewing squares together :

Info :

After blocking, put 2 squares together with the wrong sides facing each other. Use a running stitch along the edge, threading the yarn back and forth through each stitch. When you get to the "ch 3" corners, sew the first ch st. When you unfold the squares, you should see a double braided texture at the seam.

— Assembly :

Info :

The Cornflower Sweater is meant to be oversized, so the dimensions are not intended to be exact. Choose the dimensions that you feel suit you best, and don't be afraid to overshoot the measurements for a draping, graceful look. Make two panels that look like the diagram: one will be the front panel, and one will be the back. Line up your front and back panels and sew them together along the indicated seams to create arm openings and shoulder connections. Weave in any stray ends.

Assembly Instructions

  • Block all squares to even out shape and size before assembly for best results.
  • Arrange squares into two panels (one front, one back) following the diagram layout and desired width and arm span.
  • Place two squares wrong sides together and use a running stitch along the edge, sewing back and forth through each stitch; at the 'ch 3' corner, sew the first chain to secure the corner.
  • Sew front and back panels together along the dotted seams shown in the diagram to form shoulder seams and side seams, leaving arm openings as indicated.
  • When you unfold the sewn squares, ensure you see the double braided texture at each seam for a clean finish.
  • Weave in any stray ends with a yarn needle after all seams are complete.

Important Notes

  • 💡Chains at the beginning of rounds count as stitches—remember this when counting stitch totals and closing rounds.
  • 💡Block each square to the approximate 8-inch measurement before sewing to ensure even seams and garment dimensions.
  • 💡Work with consistent tension for all squares so they match in size and appearance when assembling panels.
  • 💡Place wrong sides together when sewing squares so the running stitch will create a double-braided seam when unfolded.

This Cornflower Sweater pattern celebrates relaxed, oversized style with floral crochet motifs you can make and assemble at your own pace. The framed triple-crochet edges add structure to lacy petals, and the sewn seams reveal a beautiful braided finish. Make it your own by adjusting the number of squares and blocking for the perfect drape. 🧶✨
