Floral Medallion Granny Square Crochet Blanket Pattern

Introduction

This visually striking crochet project features a large, rectangular blanket crafted from repeated floral medallion granny squares. Warm caramel brown dominates the design, with pretty cream accents forming a circular flower center on each square. Each square bursts with dimensional petals radiating from the center, encased in intricate openwork corners that keep the motif light and lacy, yet bold. When joined together, these squares create a textured, inviting surface with plenty of visual depth and interest. The finished blanket is perfect for topping a bed, using as a luxurious sofa throw, or draping over a favorite armchair. Not only is the result stunningly decorative, but the process of making each square offers satisfying variety, making it an enjoyable and engaging project for those looking to challenge their crochet skills and create a truly heirloom-worthy piece.

What makes this project particularly appealing is its blend of texture and geometry. The raised petals provide a 3D effect enhanced by the lighter, fluffy flower centers, and yet the edges of each square are crisp, allowing for seamless joining. The earthy color palette suits modern boho and rustic styles alike, but the motifs would look equally amazing in more vibrant or pastel shades. Whether you gift it or keep it for yourself, this blanket is sure to stand out in any setting.

Project Overview

This crochet blanket is composed of multiple separately crocheted granny squares, each featuring a large central flower motif with puff stitches or bobbles at the center, petal textures, open lacy corners, and solid edges. The squares are joined together in the final assembly to create one large, cohesive blanket. A decorative border or edging is added once all the squares are assembled, further enhancing the blanket’s visual appeal and helping even out the edges for a professional finish. The construction includes working in the round for the square motifs, utilizing post stitches for petal texture, and changing yarn colors at the flower center.

Granny squares: Worked individually in rounds, then joined.
3D flower motif: Central bobble or puff-stitched circle, radiating textured petals.
Lacy corners and classic square edges: Keep the blanket light and visually appealing.
Border: Worked around the assembled blanket for a finished look.

Skill Level

Intermediate. This project is best suited for crocheters with experience in working in the round, reading patterns, and using post stitches, bobbles, or puff stitches. Joining granny squares and working an even border are required, as is changing yarn colors neatly. Beginners comfortable with simple granny squares may find this a good challenge.

Materials

Yarn: Worsted weight (Category 4) cotton yarn. Choose high-quality, soft yarn with crisp stitch definition. Approximate requirements:

Main color (MC, brown): 1,800–2,200 g (64–78 oz) for a full queen-sized blanket (adjust per desired size).
Accent color (AC, cream/white for flower centers): 200–250 g (7–9 oz).

Crochet hook: US Size H-8 (5.0 mm) or size needed to achieve gauge.
Tapestry needle: For weaving in ends and sewing squares together.
Sharp scissors
Stitch markers: To mark corner stitches or track joining on large projects.
Measuring tape: For checking square size and finished blanket measurements.
(Optional) Blocking mats and pins: For shaping squares and the finished blanket.

Finished Size

The finished blanket as shown covers the top and sides of a queen-sized bed, approximately 220 cm x 240 cm (87″ x 95″). Each granny square measures about 22 cm (8.5″) per side when blocked. You can customize the size by adjusting the number of granny squares made and joined. For a smaller lap throw, use fewer squares; for a king-sized blanket, make and join more. Adjusted individual square size by changing hook size or yarn thickness.

Gauge

One completed granny square motif (blocked) should measure approximately 22 x 22 cm (8.5 x 8.5 inches). To check your gauge, complete one square and measure it flat. Differences in gauge will affect the overall blanket size and yarn amounts needed. Adjust hook size as necessary to meet gauge, especially if aiming for a specific finished measurement or using a different yarn.

Pattern Notes

Ch 3 at the beginning of a round counts as the first dc unless otherwise specified.
All squares are worked in joined rounds; each round ends with a sl st into the top of starting ch or stitch.
Use stitch markers to mark each square’s corners, especially when joining.
For puff stitches: [Yo, insert hook in indicated st, yo and pull up a loop] 4 times, yo and pull through all 9 loops, ch 1 to close the puff.
Change color at the beginning of a new round as instructed. Fasten off and weave in ends neatly at each color change or carry yarn along the back when preferred.
Right side faces outward for each square. Check for consistent orientation when assembling.
Blocking is highly recommended for each square to ensure straight edges and a professional finish before joining.

Crochet Pattern Instructions

Center Flower (Make with Accent Color)

With accent color (cream), make a magic ring (MR). Ch 1 (does not count as st).
Round 1: Work 8 sc into MR. Sl st to first sc to join. (8 sts)
Round 2: Ch 1, make 1 puff st in same st, ch 1, *puff in next st, ch 1*; rep from * to * in each sc around (8 puffs, 8 ch-1 spaces). Join with sl st to the top of first puff st. Fasten off accent color. (8 puffs, 8 ch-1 spaces)

Petal Motif (Main Color)

Attach main color (brown) in any ch-1 space from previous round.
Round 3: Ch 3 (counts as dc), (2 dc, ch 2, 3 dc) in same space (first petal base). *In next ch-1 sp, 3 dc, ch 2, 3 dc*; rep from * to * around. Join to starting ch-3. (8 petal bases)
Round 4: Sl st into next 2 dc and ch-2 sp, (ch 2, dc, tr, dc, ch 2, sl st) in same ch-2 sp for one petal. [Sl st to next ch-2 sp, ch 2, dc, tr, dc, ch 2, sl st] in each ch-2 sp around for petals. Join. (8 petals)

Petal Embellishment & Smoothing

Round 5: Working behind petals, ch 1, *sc in space between each petal’s base, ch 3*; rep from * to * around. Join to first sc. (8 sc, 8 ch-3 spaces)
Round 6: In each ch-3 sp: (sc, hdc, dc, hdc, sc). Sl st into next sc. Repeat around. Join and fasten off.

Square Formation & Lacy Corners

Round 7: Attach yarn in any st after a petal. Ch 3 (counts as dc), dc in same st, ch 2, 2 dc in same st (first corner made). *Dc in next 5 sts, hdc in next 3 sts, dc in next 5 sts, (2 dc, ch 2, 2 dc) in next st (corner)*; rep around. Join with sl st to top of ch-3. (4 corners per square, each spanned by 2 dc, ch 2, 2 dc; 5 dc and 3 hdc between corners)
Round 8: Sl st to ch-2 sp of corner, (ch 3, dc, ch 2, 2 dc) in corner, *dc in each st to next corner, (2 dc, ch 2, 2 dc) in corner*; rep around. Join and fasten off. (Corners reinforced, square shape defined)

Optional: Additional Rounds for Larger Squares

If you wish to make larger squares, continue working additional rounds as in Round 8, placing (2 dc, ch 2, 2 dc) in each corner and 1 dc in each stitch along the sides. With every round, side stitch counts increase by 8 (2 additional dc per side per round).

Make Multiple Squares

Repeat the motif instructions for as many squares as needed for your blanket size. For a queen-sized blanket, you may need 6 squares across and 7 squares down (total: 42 squares), but adjust as needed for desired fit.

Joining Squares

Arrange squares in desired layout, ensuring all have the RS facing up and flower centers aligned.
Use your preferred method to join squares. Options include:

Whipstitch: With WS together, whipstitch through back loops only.
Single crochet join: Join squares with sc through both layers’ outer loops with RS facing out.
Continuous join-as-you-go: If you prefer, you may join new squares to the blanket in the last round using slip stitches or sc at the appropriate stitches of already joined squares.

Border

Once all squares are joined, work a simple border to frame and straighten edges:
Attach main color to any corner with a sl st. Ch 3 (counts as dc), (dc, ch 2, 2 dc) in same corner, *dc in each st across to next corner, (2 dc, ch 2, 2 dc) in corner*; rep around. Join with sl st.
Optional: For a lacier edge, in the next round, (ch 5, sk 2 sts, sc in next st) around, working (ch 5, sc) twice in each corner. Join and fasten off.

Assembly and Finishing

Carefully lay all blocked squares out according to your desired pattern on a flat surface, ensuring all right sides face up and motifs are symmetrically arranged. Use stitch markers to keep rows and columns in order, especially for larger blankets. Begin joining squares row by row or column by column, joining at edge stitches to minimize seams. Take time aligning petal edges and corner stitches for a seamless look. Once the main body is assembled, work the border evenly around, maintaining even stitch counts at corners. Weave in all ends securely using a tapestry needle, hiding any visible yarn tails neatly inside stitches. Lastly, block the blanket flat—pin it to shape on foam mats, mist lightly with water, and allow it to dry completely. This relaxes the fabric and gives the entire project a crisp, professional finish.

Customization Ideas

Color Play: Swap the brown for any neutral, pastel, or bold color. Choose multiple flower center accent colors for a rainbow garden effect or a faded ombre look.
Alternative Yarns: Use acrylic, wool, or a blended fiber for different texture and warmth.
Adjust the Size: Add or subtract squares to fit a twin, throw, or king-sized bed. Vary yarn weight and hook size for smaller or larger motifs.
Home Décor Uses: Use a single square as a decorative pillow cover, join four for a table topper, or make a scarf or shawl with a row of floral motifs.

Troubleshooting

Curling Square Edges: Make sure you block each square before joining. Slight curling is common and will usually relax after blocking.
Uneven Corners: Ensure you consistently place the same number of corner stitches (2 dc, ch 2, 2 dc) in every corner; use a stitch marker to mark corners if needed.
Blanket Too Large/Small: Double check your gauge before making all squares. Adjust hook size up or down as needed if squares are not matching intended measurements.
Loose Color Changes: Fasten off and weave ends securely after color changes to prevent flower centers coming undone.
Uneven Petal Texture: Be consistent in tension, especially for post stitches and puff stitches. Practice making a few petals before assembling the full square if necessary.

Care Instructions

Wash your finished crochet blanket as recommended for your chosen yarn. For cotton or acrylic: machine wash gently in cold or lukewarm water; lay flat to dry to prevent distortion. If hand washing, soak in a gentle detergent, squeeze out water without wringing, then block flat to shape. Avoid bleach and high heat to maintain color and shape.

Final Notes

For the best results, regularly count your stitches after each round to keep your squares even and symmetrical. Don’t hesitate to adjust your tension or switch hooks if your squares are too loose or tight. Use the project photo as a visual reference, and enjoy the process of assembling a truly unique, beautiful crochet blanket you’ll cherish for years to come.
