Sure! Here’s a detailed step-by-step guide on how to crochet a classic round bag using T-shirt yarn (also known as T-yarn or recycled jersey yarn). This kind of bag is trendy, sturdy, and eco-friendly.

👜 How to Make a Classic Round Crochet Bag with T-Shirt Yarn
🧶 Materials Needed:
- T-shirt yarn (2-3 rolls depending on the size and thickness)
- Crochet hook (8 mm – 10 mm, depending on your yarn thickness)
- Scissors
- Yarn needle or tapestry needle
- Bag handles (optional: leather straps or crochet handles)
- Magnetic clasp or zipper (optional, for closure)
- Stitch marker (optional, to mark beginning of rounds)
- Lining fabric and sewing kit (optional, if you want a fabric lining)
🧵 Pattern Overview
You’ll be making two round panels, joining them together, and adding straps or hardware.

🧩 Step-by-Step Instructions:
🔵 Step 1: Crochet the Round Panels (Make 2)
You will crochet two flat circles. Use a spiral method (no joining at end of each round) or join each round with a slip stitch—up to you.
✅ Round Circle Base Pattern:
Round 1:
Make a magic ring, ch 1, and crochet 6 single crochets (sc) into the ring.
Tighten the ring. (6 stitches)
Round 2:
2 sc into each stitch around. (12 stitches)
Round 3:
1 sc in next stitch, 2 sc in next — repeat around. (18 stitches)
Round 4:
1 sc in next 2 stitches, 2 sc in next — repeat around. (24 stitches)
Round 5:
1 sc in next 3 stitches, 2 sc in next — repeat around. (30 stitches)
➡️ Continue this increasing pattern:
- Each round increases the number of single crochets between the increases by 1.
- Keep going until your circle is the desired diameter (usually 8–12 inches for a classic bag).
🔁 Example: If you want a 10” diameter bag, you may stop at 9–10 rounds.
Tip: Use a stitch marker to mark the first stitch of each round.

🟤 Step 2: Create the Sides (Optional)
If you want your bag to have depth (i.e., not just two flat circles), you can crochet a side band.
How:
- Chain enough stitches to match the circumference of your round panel.
- Join with slip stitch to form a ring.
- Crochet in rounds (sc or hdc) until it’s the desired width (2–4 inches).
- This piece will be sewn between the two round panels.
🧵 Step 3: Join the Two Circles
There are two options:
Option A: Flat Bag
- Place the two circles wrong sides together.
- Use slip stitches or single crochet through both loops of both panels to join them around the edge.
- Leave the top 1/4 open for inserting items (or fully close if you want a zippered pouch style).
Option B: Add Side Band
- Sew or crochet one edge of the side band to one circle, and the other edge to the second circle.
🧷 Step 4: Add Closure
You can attach:
- A magnetic clasp in the inner top center.
- A zipper (sewn into the top opening).
- Or use a button and loop closure.
🪡 Step 5: (Optional) Add Fabric Lining
To give your bag more structure and prevent stretching:
- Cut two circles of fabric the same size as your crochet circles.
- Cut a long rectangle for the side (if using a side band).
- Sew lining pieces together.
- Hand-stitch or machine-sew the lining inside the crochet bag using a needle and thread.

👜 Step 6: Attach Straps
Options:
- Use leather or faux-leather straps (with rivets or sewn).
- Crochet handles using T-shirt yarn:
- Chain the length you want.
- Work 1-2 rows of single crochet or half-double crochet.
- Attach to the inside top edge of the bag.
