How to Crochet a 3D Daisy Granny Square
ad 26 3
For a cardigan similar to the photograph, make floral squares with white or pale-blue petals and different shades of blue around the flowers. A dark navy border helps the finished garment look coordinated.
Step 1: Make the Flower Center
With your chosen center color, make a magic ring.
-
Chain 1.
-
Work 12 single crochet stitches into the ring.
-
Pull the ring closed and join with a slip stitch to the first single crochet.
-
Fasten off if you want to change colors.
You should now have a small, firm circle for the middle of your daisy.
Step 2: Crochet the Raised Petals
Attach white yarn to a stitch in the center.
For a simple raised petal, work the following into the same stitch:
-
Chain 2.
-
Work 2 double crochet stitches.
-
Chain 2.
-
Slip stitch into the same stitch.
Repeat around the flower center, spacing the petals evenly. Depending on the size of your center and the look you prefer, you may need to adjust the number of petals or the stitches in each petal.
This creates a textured flower. For a fuller, puffier daisy, use a puff-stitch or cluster-style petal instead.
Step 3: Turn the Flower Into a Square
Attach a contrasting blue yarn in a space between two petals.
-
Chain 3 to count as the first double crochet.
-
Work double crochet stitches around the flower, using the spaces between petals to form the corners.
-
At each corner, work a corner group of 3 double crochet stitches, chain 2, and 3 double crochet stitches into the same corner space.
-
Work along each side with evenly spaced double crochet groups.
-
Join the round with a slip stitch.
If the square still looks rounded, add another round of double crochet groups, keeping the four corners consistent.
Step 4: Add the Final Border
Use navy blue or another dark shade for the last round.
Work double crochet groups along the sides and the usual corner groups at each corner. Finish with a slip stitch and fasten off.
Measure your square and make sure all your motifs are approximately the same size. Consistent squares make joining much easier.
Planning the Cardigan Size
Before making all your motifs, decide how long and wide you want the cardigan to be. The number of squares depends on the finished size of each motif and the wearer’s measurements.
| Area | How to plan it |
|---|---|
| Back | Arrange squares in a rectangle wide enough for the back |
| Front panels | Make two separate panels, allowing room for the open front |
| Sleeves | Join squares into two tubes or rectangular sleeve panels |
| Cuffs | Add a few rounds of single crochet or ribbed crochet |
| Lower hem | Add a border to create a neat, finished edge |
For a larger cardigan, use more squares or make each square bigger. For a shorter jacket, reduce the number of rows in the body.
Helpful tip: Lay your squares out on a flat surface before joining them. This allows you to balance the colors and avoid placing too many identical motifs together.
