Which stitch to choose for a t-shirt yarn or cord bag depending on the shape
Share
The same material can create a firm or a soft bag simply by changing the stitch. In this guide, you'll learn which stitches work best depending on the shape (basket, sack, rectangular, clutch, tote, etc.), and how to avoid common problems: wavy edges, sagging sides, and bags that lose their shape.
Are you starting a bag and unsure about the knitting?
Choosing the right starting point is what prevents having to "fix" the structure at the end.
Quick criteria: shape + use + fall
Before thinking about "what stitch looks nice," decide what you need the bag to do:
- Structure: Do you want it to stand upright and retain its shape?
- Flexibility: Do you want a soft bag that adapts to your body?
- Friction: Will it be attached to clothing (daily use) or will it be a clutch/occasion?
- Weight: Will you be carrying a little or a lot? The more weight, the more convenient a compact point is.
Quick rule: geometric shape + everyday use + weight = compact point . Organic shape + bucket bag + relaxed look = point with more drape .
Most commonly used stitches in handbags (and what they offer)
Low point (LP)
The winning basic for t-shirt yarn and cord: compact, resistant and with good shape control.
- Ideal for: structured bags, baskets, rectangular bags, and body totes.
- Finish: solid, regular, with a marked texture.
- Note: It may become rigid if you tighten the tension too much.
Centered low stitch / waistcoat stitch (centered low stitch)
It gives a very "knitted" look, almost like needlepoint, and usually provides more body and less hollowness than regular single crochet.
- Ideal for: premium handbags, structured clutches, geometric pieces.
- Finish: very clean and uniform.
- Note: It consumes more material and is slower.
Relief stitch / BLO rib (back loop only)
Knitting by picking up only the back loop creates horizontal lines and a fabric that flexes in a controlled way.
- Ideal for: textured walls, basket-style bags with lines, pieces that need to "complement" without collapsing.
- Finish: modern, with linear relief.
- Note: It may give a little more elasticity; compensate for this at the top edge.
Mid-high / high point
It rises faster, but leaves more "air." In handbags, it's often used when you're looking for lightness or a softer effect.
- Ideal for: soft drawstring bags, summer shoppers, lined bags (because the lining provides structure).
- Finish: more flexible, less compact.
- Note: If the bag is unlined and heavy, it may become deformed.
Openwork and chain stitches
Visually light and very pretty, but they require a strategy to prevent them from losing their shape.
- Ideal for: beach bags, lightweight shoppers, decorative pieces.
- Essential: lining or reinforcement in stress areas (handles and top edge).
Which stitch to choose according to the shape of the bag
Here's a "shape → recommended point" guide to help you decide without doubt:
| Bag shape | Recommended spot | Because | Extra tip |
|---|---|---|---|
| Rigid basket/bag | PB or centered PB | Maximum compaction and shape control | Finish the top edge with a compact turn-up. |
| Rectangular / geometric | PB centered or PB | Definition of stable edges and sides | Rigid base if you want perfect angles |
| Bucket bag / drawstring bag | PB + BLO section (optional) | Body without “collapse”, with controlled fall | Reinforces the gathering/buttonhole area |
| Clutch / nozzle | Centered PB or very regular PB | You need a sturdy wall to "fit" the latch. | Add interlining/lining for premium finish |
| Tote / shopper | PB (or medium high if there is a lining) | Balance between resistance and speed | Handle anchors with inner patch |
| Soft bag / “soft” style | Mid-high / high + lining | More drooping and visual lightness | Upper edge stabilized, no matter what |
| Draft (beach, summer) | Chain stitches (with strategy) | Lightweight and decorative | Lining and reinforcement on handles/edge |
Mental shortcut: If your bag has edges (straight lines, corners, defined base), prioritize PB or centered PB. If your bag is organic (sack, soft), you can broaden your options.
Typical mistakes when choosing a point (and solution)
Error 1: Choosing a high point for a bag that needs structure
Result: soft walls, a bag that deforms, and a rim that opens.
Solution: switch to PB (or centered PB) or add lining + compacted top edge.
Error 2: stitch too “tight” in elastic t-shirt yarn
Result: stiff fabric, difficult to knit, sides that curl or "shrink".
Solution: Adjust tension, try a slightly larger crochet hook, and keep the same stitch.
Error 3: unreinforced cut
Result: the handle pulls, the edge opens and the bag "lengthens".
Solution: lining + inner patch on anchors + compact top turn.
Error 4: not thinking about the basics
Result: a geometric bag that doesn't maintain its angle.
Solution: compact point + rigid base (if you're looking for "perfect shape").
Fine adjustments: tension, hook and structure
- If the fabric ripples: this is usually due to excessive increases or too loose a tension. Check the base increases and slightly tighten the tension.
- If the fabric is buckling: you need more increases or the tension is too tight. Adjust the increases or switch to a slightly larger crochet hook.
- If the walls give way: make the point more compact (ground floor/ground floor centered), or add lining/structure.
- If the top edge opens: 1–2 compact turns + reinforcement in the handle area (inner patch).
Practical tip:
The "perfect" stitch is the one that maintains its shape under actual weight . Make a small sample at your chosen stitch, hang it with a little weight, and see how it behaves.
FAQ
PB or centered PB for a rectangular bag?
If you want a very uniform finish with a premium look, use centered PB. If you're looking for speed and strength with a good shape, use standard PB. In both cases, reinforce the top edge and anchors.
Does the cord stay more secure than the t-shirt yarn?
In general, a cord tends to produce a more defined wall, especially with tight stitches. Even so, the stitch and tension are what most significantly affect the result.
I want a bag that stands upright without "cardboard", what do I do?
Choose PB or centered PB, adjust tension for a compact fit, and add a lightweight rigid base if you want a perfect bottom. A tightly folded top edge helps a lot.
Can I mix and match stitches in the same bag?
Yes, and it's a very good strategy: base and first rounds in compact stitch for stability, and then texture (BLO, relief or some decorative section) without compromising the structure.
