The Heirloom Bouquet Square: A Floral Center Granny Square Pattern

Introduction: Blooms & Blocks, The Perfect Pairing

Hello, crochet lovers! Today we are diving into a project that beautifully blends two classic techniques: the elegance of floral motifs and the timeless simplicity of the Granny Square. I’ve named this the Heirloom Bouquet Square because its center is a delicate, layered flower that blooms outward into a sturdy, easy-to-join block.

This square is perfect for adding a touch of romance and texture to any project. Whether you are looking to stitch together a stunning blanket, craft a unique cushion cover, or create decorative bunting, this pattern is fast, fun, and highly customizable with color.

Grab your favorite scrap yarns and let’s turn simple yarn into a gorgeous, lasting treasure!

Section 1: Materials & Tools

This square works best with contrasting colors to make the floral center truly pop.

Yarn	Worsted Weight (Category 4) or DK Weight (Category 3)	Using the same weight for all colors ensures consistent sizing.
Color A	Center Flower Color (e.g., Yellow or Bright Pink)
Color B	Petal/Background Color (e.g., White or Light Green)
Color C	Main Square/Joining Color (e.g., Neutral or Dark Blue)
Hook	Size I/9 (5.5 mm) or H/8 (5.0 mm)	Choose a hook appropriate for your yarn weight. Hook size determines square size.
Notions	Yarn needle for weaving in ends, scissors.

Finished Size (Approximate):

Using Worsted Weight yarn and a 5.5 mm hook, the finished square after 5 rounds will measure approximately 6 x 6 inches (15 x 15 cm).

Section 3: The Pattern – Heirloom Bouquet Square

Part A: The Floral Center (Color A)

The first two rounds establish the tight center of the flower.

Round 1:

Using Color A, start with a Magic Ring (MR).
CH 3 (counts as 1st DC).
DC 11 into the ring.
Pull the tail tight to close the ring. SL ST to the top of the starting CH 3 to join. (12 stitches)
Fasten off Color A.

Round 2: Defining the Petals (Color B)

Attach Color B with a SL ST to any stitch of Round 1.
CH 3 (counts as 1st DC). DC 2 into the same stitch.
CH 1.
*Skip the next stitch. DC 3 into the next stitch. CH 1.*
Repeat from * to * five more times.
SL ST to the top of the starting CH 3 to join. (6 DC 3-stitch clusters, 6 CH 1 spaces)
Fasten off Color B.

Part B: Squaring the Circle (Color C)

This is the key round where we transition the 6-sided flower into a 4-sided square using a combination of HDC, DC, and TC stitches.

Round 3: The Corner Foundation (Color C)

Attach Color C with a SL ST into any CH 1 space from Round 2.
Side 1: CH 2 (counts as 1st HDC). HDC 2 into the same CH 1 space. (3 HDC total)
Side 2: In the next CH 1 space, work DC 3.
First Corner: In the next CH 1 space, work (TC 3, CH 2, TC 3). (This wide TC cluster forms the first corner)
Side 3: In the next CH 1 space, work DC 3.
Side 4: In the next CH 1 space, work HDC 3.
Second Corner: In the final CH 1 space, work (TC 3, CH 2, TC 3).
SL ST to the top of the starting CH 2 to join. (4 Corners now established)
Fasten off Color C (optional if you want the next round in a different color, otherwise continue).

Self-Check: At the end of Round 3, you should have 4 corners formed by TC clusters and two sides made up of a DC cluster and an HDC cluster.

Part C: Growing the Granny (Color C or New Color)

From here, we use the standard Granny Square technique (DC 3 clusters) to expand the square to your desired size.

Round 4: First Granny Round

If you fastened off, attach your yarn (e.g., Color C) with a SL ST to any CH 2 corner space.
CH 3 (counts as 1st DC). Work (DC 2, CH 2, DC 3) into the corner space. (This is the new corner block)
CH 1 (separates the clusters).
Skip the next space (the TC 3 cluster). Work DC 3 into the space between the TC clusters and the DC/HDC clusters of the previous round.
CH 1.
Work DC 3 into the next available space (between the HDC and DC clusters).
CH 1.
Work DC 3 into the final space before the next corner.
CH 1.
Corner Repeat: Work (DC 3, CH 2, DC 3) into the next CH 2 corner space.
Repeat Steps 3-9 around. SL ST to the top of the starting CH 3 to join.

Round 5 and Beyond: Standard Granny

SL ST into the next 2 DC, and then SL ST into the first CH 1 space.
CH 3 (counts as 1st DC). DC 2 into the same space.
CH 1.
Work DC 3 into every CH 1 space along the sides of the square, separating each cluster with a CH 1.
Corner Repeat: Work (DC 3, CH 2, DC 3) into every CH 2 corner space.
Repeat this round until your square reaches the required size.

Finishing: Fasten off and use your yarn needle to weave in all ends securely on the back of the square. For a crisp finish, lightly block your square using water and pins.

Section 4: Project Ideas & Customization

This versatile square is wonderful on its own, but its true potential shines when combined with others!

Project Inspiration:

The Cottage Blanket: Join several squares together to create a lightweight, airy blanket. Use a neutral color for the outer rounds to make joining easier.
Bohemian Bag: Join 9 squares (3×3) to form a simple shoulder or tote bag.
Decorative Pillow: Stitch four large squares together (two for the front, two for the back) for an elegant cushion cover.

Color Customization Tips:

High Contrast: Use bright, bold colors for the flower center (A & B) and a dark, solid color for the final square rounds (C).
Ombre Effect: Use three shades of the same color family (light, medium, dark) for A, B, and C to create a subtle gradient effect.
Scrap Buster: Use a different scrap yarn for every single round to create a truly unique, multi-colored piece.

I hope you love crocheting this beautiful square as much as I do! Don’t forget to share your finished Heirloom Bouquet Squares with the crafting community! Happy hooking!
