Making Sunflower Granny Square

A. White Center

Form a Magic Ring:
Wrap brown yarn around two fingers. Insert hook under first strand, catch the second, form a “U,” then catch the rear strand and pull through to make a loop; slide off fingers.
Round 1:
- Ch 2 (does not count as st).
- Work 16 dc into the ring.
- Pull tail to close.
- Sl st into 2nd dc made.
Fasten off brown, ch 1, and cut yarn.

B. Sky Blue Petal—Puff Stitch Round

Attach yellow to any dc.

- Yarn over, insert hook, pull up loop (5 loops).
- Yarn over, insert hook, pull up loop (7 loops).
- Yarn over, pull through all 7 loops.
- Ch 1.
Rep: Work a puff st (see Special Stitches) + ch 1 in each st around (16 total).

C. Petal Round 2—Unfinished Double Crochet

Ch 2.
In each ch space, work as follows:
- In same ch space, [Yarn over, insert, pull up loop, yarn over, pull through 2] x4 (do NOT finish any dc; after 4 you have 5 loops on hook).
- Yarn over, pull through all 5 loops.
- Ch 2.
Repeat around (1 petal in each ch-space).
After last petal, ch 2, and sl st into first chain space of round.

In same chain space: (tr, tr, tr) (making 6 tr in total with ch-2 in between).
In next ch space: 3 dc.
In next ch space: 3 hdc.
In next ch space: 3 dc.
Next ch space: Repeat (corner)—6 tr with ch-2 in middle as before.

How Many Squares?

Make a total of 54 squares for a small (you may need more for larger sizes):

How to Join Squares

A. Crochet Hook Method:

With wrong side facing you, align two squares at edge.
Attach green yarn with a slip knot to hook.
Insert hook into back loops of both squares along edge (see V-shapes).
Pull working yarn through both loops and the loop on hook (sl st).
Continue across edge.
Attach next square, repeating as above. Join vertically/horizontally as preferred.

B. Yarn Needle Method:

Thread green yarn on needle.
With wrong sides together, pick up outer/top loops only.
Pull through, tie to secure.
Work across squares, sewing panels as desired.
This method creates a flatter, more invisible seam but requires more cutting/reattaching yarn.

Assembling Panels and Sleeves

Lay out all joined squares as follows:
- Back: 20 squares in rectangle.
- Fronts: 8 squares each, sewn to top sides of back panel.
- Sleeves: 9 squares sewn in strip, then to bodily panels.
Sew or crochet fronts to top of back.
Fold and attach sleeves by matching center three squares on panel.

Ribbing and Finishing Edges

Attach green yarn to bottom/edge of cardigan.
Ch 1, sc evenly around entire lower edge.
Bottom Ribbing:
- Ch 8 (adjust as desired).
- hdc in back loops only to end, sl st into next st on edging.
- At start of each new row, sl st into next 2 sts, hdc back across in BLO.
- Continue back and forth for entire hem.
Cuff Ribbing (optional):
- Repeat above for sleeves, or add 2 rows dc for a flared cuff.

Assembly & Finished Size

Sew all panels (back, fronts, sleeves) with squares wrong side (WS) together.
Attach sleeves to main body last, lining up center of sleeve strip with body seam.
Ribbing is added at the end to body hem and sleeve cuffs.
Finished size (S) is approx. 5”/13cm per square; adjust number/arrangement for your size.
Try on for fit before seaming sides and sleeves completely.
Weave in all ends on inside.
