What Makes This Vintage Wildflower Granny Square Cardigan Special
This cardigan achieves its sophisticated yet effortless look through a clever combination of traditional floral motifs and modern assembly techniques.

The open-front boxy silhouette is framed by crisp, half-double crochet ribbed cuffs and a matching bottom band, providing a tailored contrast to the soft geometry of the retro wildflower squares.

Yarn Suggestions
| Yarn Brand & Line | Weight | Yards per Skein | Notes |
|---|---|---|---|
| Peru Wool Classic | Worsted | 100 yds / 50g | Excellent stitch definition, provides an authentic rustic feel. |
| Cascade 220 | Worsted | 220 yds / 100g | Wide earthy color palette, wonderful drape after blocking. |
| Lion Brand Wool-Ease | Aran / Worsted | 197 yds / 85g | Budget-friendly acrylic-wool blend with great durability. |
⚠️ Note: Avoid using 100% slick mercerized cotton for this project; the lack of elasticity causes the cardigan squares to stretch out and sag over time. Stick to wool, wool blends, or high-quality acrylics with good memory.
Gauge
| Measurement Type | Stitch / Row Count | Motif Dimension |
|---|---|---|
| Square Gauge | 1 Motif = 5.5 in x 5.5 in (14 cm x 14 cm) | After gentle blocking |

Pattern Instructions
Section 1: The Wildflower Motifs (Make Multiple)
Make squares following the color distribution chart below. Each square measures 5.5 inches across.
– Size XS-S: Make 38 squares total.
– Size M-L: Make 46 squares total.
– Size XL-2XL: Make 54 squares total.
Round 1: With Color B (Terracotta), start with a magic ring. Ch 3 (counts as first dc), work 2 dc in ring, ch 2, [3 dc in ring, ch 2] 3 times; join with sl st to top of beg ch-3. Fasten off. (12 dc, 4 ch-2 sps)
Round 2: Join Color C (Mustard) in any ch-2 corner sp. Ch 3, (2 dc, ch 2, 3 dc) in same corner sp, *ch 1, skip 3 dc, (3 dc, ch 2, 3 dc) in next corner sp; rep from * around, ch 1, join with sl st to top of beg ch-3. Fasten off. (24 dc, 4 ch-1 sps, 4 ch-2 corners)*

Ch 3, (2 dc, ch 2, 3 dc) in same corner sp, *ch 1, skip 3 dc, 3 dc in next ch-1 sp, ch 1, skip 3 dc, (3 dc, ch 2, 3 dc) in next corner sp; rep from * around, ending with ch 1, join with sl st to top of beg ch-3. Fasten off. (36 dc, 8 ch-1 sps, 4 ch-2 corners)*
Round 4: Join Color D (Oatmeal) in any ch-2 corner sp.

Fasten off, leaving a 12-inch tail for seaming. (48 dc, 12 ch-1 sps, 4 ch-2 corners)*
✅ Checkpoint: Block all finished motifs to identical 5.5-inch squares before moving on to assembly. Consistent blocking makes the whipstitching process infinitely smoother.
Section 2: Layout and Assembly
Arrange your blocked squares according to the garment schematic:
– Back Panel: 3 rows of 4 squares (Sizes XS-S) or 3 rows of 5 squares (Sizes M-L) or 3 rows of 6 squares (Sizes XL-2XL).
– Front Panels (Make 2): 3 rows of 2 squares (Sizes XS-S) or 3 rows of 2.5/3 squares depending on sizing grade.
– Sleeves (Make 2): 2 rows of 3 squares tapered to the wrist.
Using the tapestry needle and the yarn tails left from Round 4, whipstitch the squares together along the edges with RS facing out, matching corner to corner. Seam the shoulder seams first, then attach the sleeves to the armhole openings, and finally seam the side/underarm seams.
Section 3: Bottom Hem and Front Band Ribbing
Row 1: With RS facing, join Color D (Oatmeal) at the bottom right front corner. Ch 2 (does not count as st), work hdc evenly up the right front opening, across the back neck, and down the left front opening, ending at the bottom left corner. Turn. (Stitch count varies by size)
Rows 2–6: Ch 1, working in BLO, hdc in each st across, turn. (Stitch count matches Row 1)
Fasten off and weave in all remaining ends securely.
Section 4: Sleeve Cuffs
Row 1: With RS facing, join Color D (Oatmeal) at the underarm seam of one sleeve opening. Ch 2, work hdc evenly around the entire cuff circumference, join with sl st to first hdc. Turn. (32 hdc)
Rows 2–5: Ch 1, working in BLO, hdc in each st around, join with sl st to first st, turn. (32 hdc)
Fasten off. Repeat for the second sleeve cuff.
Size Customization Tips
- Adjusting Length: To make the cardigan longer, add an extra horizontal row of granny squares to the bottom of the body panels before adding the bottom ribbing band. Each row adds 5.5 inches (14 cm) of length.
- Adjusting Width: To increase the bust circumference, add one additional vertical column of squares to the back panel and one column to each front panel, adjusting the overall stitch count by 5.5 inches per column added.
Care Instructions
Hand wash gently in cool water with a mild wool-safe detergent. Do not wring or twist. Roll the cardigan gently in a clean towel to press out excess moisture, then lay flat to dry on a blocking mat, reshaping to original measurements. Do not iron.
