🧵 Why Nautical Polyester Yarn?

Nautical or polyester macramé yarn is:

Strong and stiff, helping your bag hold shape
Water-resistant, perfect for outdoor or beach use
Slightly shiny, giving a polished, modern look
Available in various thicknesses (we recommend 4mm–6mm for bags)

🧶 It’s tougher than cotton, so take breaks and use an ergonomic hook to avoid hand fatigue.

👜 Part 1: Make the Flower Granny Squares

We’ll use flower granny squares as the main panels for the front and back of the bag.

🌼 Step 1: Crochet the Flower Center

With Color A (flower center),
- Ch 4, sl st into first ch to form ring.
- Ch 2 (counts as dc), work 11 dc into ring (12 dc total).
- Sl st to join, fasten off.

🌺 Step 2: Make Petals

Join Color B (petal color):
- (Ch 3, 2 dc in same st, ch 3, sl st in same st) – petal formed.
- Sl st into next st and repeat in each stitch around.
- You’ll have 12 petals. Fasten off.

🟩 Step 3: Square Off the Flower

Join background yarn (Color C or the main bag color):
- Sl st behind a petal into a space between petals.
- Begin the granny square pattern:
  (3 dc, ch 1) between corners, and
  (3 dc, ch 2, 3 dc) in the four corners.
- Make 2 or 3 rounds to create a square measuring 5–6 inches.

🧶 Make 4–6 flower squares depending on your desired bag size.

🧱 Part 2: Assemble the Bag Panels

🧵 Step 1: Lay Out the Squares

Arrange your squares:

2 squares across = width
2 squares tall = height

👉 Use more if you want a larger tote-style bag.

🧵 Step 2: Join Squares

Use slip stitch, single crochet join, or whip stitch.
Keep right sides facing outward for a flat seam.
Join both front and back panels separately.

🧵 Step 3: Make the Side & Bottom Panel

For a structured shape, crochet a long rectangle for the bag’s side and bottom.

Pattern:

Ch 10 (for side width),
Sc in each row until the panel is long enough to wrap around the bottom and both sides of the bag (typically ~80–100 rows).
This gives the bag a boxed shape and depth.

🧵 Step 4: Join All Panels Together

Attach side/bottom strip to the front panel using sc or sl st.
Then attach the back panel the same way.
You should now have a complete open-top bag body.

🧳 Part 3: Create the Flap Closure

The flap is made as an extension of the back panel, folding over the front.

🧵 Step-by-Step Flap

With yarn attached to the top edge of the back panel,
Ch 1, sc across top edge only (approx. 24–30 stitches)
Turn and repeat sc rows for 6–8 inches depending on desired flap length
Optional: Create a pointed flap by decreasing 1 st at each end every 2 rows
Optional: Add a flower appliqué on the flap

🧲 Leave a gap or loop if using a button closure.

🪡 Part 4: Add the Lining

Lining adds structure and prevents items from slipping through the crochet stitches.

🧵 Steps to Add a Lining:

Lay the bag flat and measure its width and height.
Cut fabric for:
- 2 rectangles (for front and back)
- 1 long strip (for side/bottom)
- 1 piece for flap
Sew the fabric panels together like a pouch.
Place inside the crochet bag.
Use needle and thread to hand-stitch lining to the top edge of the crochet bag and flap (use small stitches to stay invisible).
Optional: Add inner pockets or zipper pouch.

🧲 Part 5: Add Closure

You can choose any of the following:

✅ Magnetic Snap

Sew the inner halves of the snap into the lining.
Place one under the flap, and one on the front panel.

✅ Button and Loop

Sew a button on the front panel.
Add a ch 15–20 loop to the flap.

✅ Zipper

Insert zipper between the lining and crochet top edge (hand-sewn or machine-sewn).

🪢 Part 6: Add the Strap

Option 1: Crochet Strap

Ch 100–120 (for shoulder strap)
Turn, sc across for 4–6 rows
Sew both ends securely to inside sides of the bag

Option 2: Chain or Leather Strap

Use grommets or D-rings
Attach store-bought strap or chain
