Originally developed by the design studio at Bernat, this clever pattern eliminates the tedious assembly of dozens of tiny granny squares. Instead, two generous 7-round statement motifs form the entire front and back of the bag. An ingenious row of Back Post Double Crochet (dcbp) worked along three sides creates an instant 3D perimeter depth, giving the bag authentic structured volume without floppy sides. A continuous border of sturdy single crochets binds the top edge and sturdy shoulder handle together for lifelong durability.

Key Materials, Yarn Specifications & Notions

Selecting a thick, high-density chenille yarn ensures that the finished tote maintains its crisp silhouette even when carried daily:

Recommended Base Yarn: Bernat Blanket (Super Bulky #6; 100% Polyester; 10.5 oz / 300 g; 220 yds / 201 m):
- Contrast A: Pink Dust (#10956) — 1 ball (approx. 110 yds / 100 m used).
- Contrast B: Sunsoaked (#10918 – warm mustard yellow) — 1 ball (approx. 150 yds / 137 m used).
- Alternative Colorways: Vintage White & Terracotta, Birch & Deep Teal, or Lilac & Olive.
Crochet Hook: Size U.S. K/10½ (6.5 mm) (or size needed to obtain gauge). A slightly tighter hook relative to blanket yarn produces firm, supportive stitches.
Tapestry Needle: Large-eye bent-tip steel yarn needle for seaming and weaving in plush chenille yarn ends.
Essential Notions: Tape measure, locking stitch markers, and sharp fabric shears.

Pattern Specifications & Working Notes

Skill Level: Beginner (Confident with basic chains, double crochet, half double crochet, and back post technique).
Finished Dimensions: Approximately 12 inches [30.5 cm] square (excluding the shoulder handle).
Gauge: 10 single crochet (sc) and 12 rows = 4 inches [10 cm]. Checking gauge ensures your motifs do not become too floppy or excessively stiff.
Beginning Chain Rule: Ch 4 at the beginning of rounds counts as 1 double crochet (dc) plus 1 chain space (ch-1 sp) throughout.
Color Switching Secret: Do not break the yarn when alternating colors across rounds! Simply carry the yarn not in use loosely along the wrong side (WS) of the work. This cuts down on weaving in dozens of bulky ends.
Special Stitch — Back Post Double Crochet (dcbp): Yarn over hook and draw up a loop around the post of the next stitch at the back of the work, inserting hook from right to left. (Yarn over and draw through 2 loops on hook) twice.

PART 2: THE 3D SIDE GUSSET BORDER

This specialized raised border creates the structural depth for the bottom and sides of the bag:

1st Row: With B, join yarn at top-left corner of first motif. Ch 2 (does not count as st). Work 1 dcbp around each hdc down the left side of Motif, 1 dcbp around each hdc along the bottom edge, and 1 dcbp around each hdc up the right side. Fasten off at top of right side.
Repeat for the second motif to create two matching 3D-edged panels.

Assembly & Final Top Edging

1. Joining the Panels: Place Front and Back Motifs with wrong sides together. Using Contrast B and your yarn needle, whipstitch or slip-stitch the raised dcbp ridges together along both sides and across the bottom edge, keeping the top open.

2. Securing the Handle: Align the short ends of the handle with the top left and right edges of the bag’s back panel. Using Contrast B, stitch both ends securely in place with reinforced backstitches.

3. Top and Handle Framing Edging: With Right Side facing, join Contrast A (Pink Dust) with sl st to the 1st hdc at top opening edge of bag. Ch 1. Work 1 sc in each st across top edge, then continue working 1 sc into each stitch (or remaining loop of foundation chain) along the long edge of the handle. Join with sl st to first sc. Fasten off and weave in all chenille ends cleanly inside the seams.

3 Atelier Secrets for Picture-Perfect Crochet Totes

1. Don’t Cut the Color Strands: When transitioning from Pink Dust to Sunsoaked, let the inactive yarn dangle down the back. Pick it up gently when needed for the next round. This eliminates bulky knot lumps inside the bag and saves 20 minutes of finishing time.

2. Keep Back Post Tension Even: When crocheting the dcbp around the perimeter, avoid pulling the loop tight against the hook. Giving the post stitch its full vertical height produces a crisp 90-degree corner that gives your bag clean structural depth.

3. Reinforce Strap Anchors with an ‘X’ Box: Rather than a single seam line, sew the handle base to the tote interior in a small 1-inch box with an intersecting diagonal ‘X’ stitch. This distributes weight evenly across the plush chenille fibers so you can safely carry laptops, produce, or heavy books.
