Materials Needed

Before you begin, gather the following supplies. This project uses worsted weight cotton yarn, which is perfect for a sturdy, washable bag that will hold its shape beautifully.

Yarn

• Color A (Sand): Worsted weight cotton yarn – approximately 100 yards
• Color B (Olive): Worsted weight cotton yarn – approximately 80 yards
• Color C (Terracotta): Worsted weight cotton yarn – approximately 50 yards

Needles and Hooks

• US 7 (4.5 mm) knitting needles – for the bag body
• US G/6 (4.0 mm) crochet hook – for the strap and drawstring

Additional Supplies

• Tapestry needle for seaming and weaving in ends
• Scissors
• Stitch markers (optional but helpful)

Gauge

20 stitches and 28 rows = 4 inches in stockinette stitch (knit one row, purl one row). Be sure to check your gauge before starting to ensure your bag fits a standard water bottle (approximately 3 inches in diameter).

Step-by-Step Instructions

This pattern is worked flat in pieces and then seamed together. Don't worry—it's simpler than it sounds! Follow along carefully, and you'll have a beautiful bottle sling in no time.

Part 1: Knitting the Bottle Bag Body

Bottom of the Bag:

1. With Color A (Sand), cast on 36 stitches using your preferred method (long-tail cast on works well).
2. Work in garter stitch (knit every row) for 10 rows. This creates a sturdy, non-curling base for your bag.
3. Increase row (right side): K1, kfb (knit front and back to increase one stitch), knit to the last 3 stitches, kfb, k1. You now have 38 stitches.
4. Work 1 row purl (wrong side).
5. Repeat the increase row every 4th row 3 more times. After all increases, you'll have 44 stitches.
6. Work even in stockinette stitch (knit right side rows, purl wrong side rows) until the piece measures 8 inches from the cast-on edge. This forms the main body of your bag.

Textured Panel:

1. Switch to Color B (Olive). This will create a beautiful textured band around the middle of your bag.
2. Row 1 (right side): Knit all stitches.
3. Row 2: Purl all stitches.
4. Row 3: *K2, p2* repeat from * to end of row.
5. Row 4: *P2, k2* repeat from * to end of row.
6. Repeat rows 1-4 until the textured panel measures 2 inches, ending with a wrong side row. This ribbed texture adds visual interest and a bit of stretch to accommodate different bottle sizes.

Top Band:

1. Switch to Color C (Terracotta).
2. Work in garter stitch (knit every row) for 6 rows. This creates a neat, finished-looking band at the top of your bag.
3. Bind off loosely. Tip: Use a larger needle or bind off loosely to ensure the top opening is stretchy enough to fit your bottle.

Part 2: Seaming the Bag

1. Fold your knitted piece in half with right sides together, matching the cast-on edge to the bind-off edge. The bag will form a flat tube shape.
2. Using your tapestry needle and a length of Color A yarn, sew the side seam using mattress stitch. This creates an invisible, professional-looking seam.
3. Important: Leave the top 1 inch of the seam open. This opening will become the casing for your drawstring.
4. Turn the bag right side out. You should now have a cylindrical bag with a flat bottom and an open top.

Part 3: Creating the Drawstring Casing

1. With Color C (Terracotta), pick up and knit 1 stitch in each bound-off stitch around the top opening. You'll be working in the round, so join carefully.
2. Work in stockinette stitch (knit every round) for 4 rounds. This creates a tube-like casing.
3. Bind off loosely.
4. Fold the casing to the inside of the bag and sew it down using your tapestry needle, leaving a small opening (about 1 inch) to thread the drawstring through later.

Part 4: Making the Drawstring

1. With Color C (Terracotta) and your crochet hook, make a slip knot.
2. Chain 24 inches. Tip: Keep your tension even for a neat, uniform chain.
3. Fasten off and weave in the ends.
4. Thread the drawstring through the casing using a safety pin or yarn needle. Pull both ends through the opening you left, and tie a simple knot or add beads for a decorative touch.

Part 5: Crocheting the Strap

1. With Color B (Olive) and your crochet hook, make a slip knot.
2. Chain 90 stitches. This will give you a comfortable shoulder-length strap. Adjust the length if you prefer a shorter or longer strap.
3. Row 1: Single crochet in the 2nd chain from the hook and in each chain across. You should have 89 single crochet stitches.
4. Rows 2-4: Chain 1, turn, single crochet in each stitch across. This creates a sturdy, slightly padded strap.
5. Fasten off, leaving a long tail (about 12 inches) for attaching the strap to the bag.

Part 6: Attaching the Strap

1. Position the strap ends on opposite sides of the bag, near the top edge. Make sure the bag hangs evenly when worn.
2. Using the long tail and your tapestry needle, whip stitch each strap end securely to the inside of the bag. Sew through both the strap and the bag fabric for a strong hold.
3. Repeat for the other strap end, ensuring the bag is balanced.

Part 7: Finishing Touches

1. Weave in all loose ends using your tapestry needle. Be sure to secure them well so they don't unravel with use.
2. Block the bag gently to shape. Wet blocking works well with cotton yarn—simply soak the bag in cool water, gently squeeze out excess, and lay flat to dry, shaping as needed.
3. Once dry, insert your water bottle, pull the drawstring closed, and sling it over your shoulder. You're ready to go!

Tips for Success

• Check your gauge: If your gauge is off, your bag may be too tight or too loose for your bottle. Adjust your needle size accordingly.
• Use stitch markers: Place markers at the increase points to keep track of your rows.
• Cotton yarn tip: Cotton has less stretch than wool, so the bag will hold its shape well but won't stretch much. Make sure your gauge matches the pattern for the best fit.
• Customize it: Feel free to change the colors to match your style, or add a button, tassel, or embroidery for extra personality.

The Wayfarer's Canteen Cozy is more than just a bottle carrier—it's a reflection of your creativity and craftsmanship. With its earthy tones and textured details, this bag is sure to become a favorite accessory. Whether you gift it to a friend or keep it for yourself, you'll love the satisfaction of carrying your water in style.

Happy knitting, and may your adventures be filled with beautiful handmade things!
