Before we begin: 3 key decisions
- T-shirt yarn or cord? T-shirt yarn usually makes a more "pleasing" bag and is quicker to knit; cord tends to give a more defined and elegant finish.
- Do you want it structured or soft? If you want a firm (box-like) shape, you'll need to choose a compact knit and consider reinforcement/lining.
- Everyday shopper (heavyweight) or lighter? A shopper that will be carried needs a reinforced top rim and handles.
Recommended materials
- T-shirt yarn or cord (ideally regular and with good body).
- Crochet hook appropriate to the thickness of the material (the important thing is that the stitch is compact, not "open").
- Markers (essential if you're going round).
- Wool needle (if you are working in pieces or for finishing).
- Optional but highly recommended: lining + rigid base (if you want structure and durability).
Tip: For a shopper, the stitching should be tight . If you see gaps between the stitches, the bag will tend to sag under the weight.
Which construction to choose: round or in pieces
Option A: round (base + walls)
Ideal if you want a bag with no side seams, quick and practical. It works very well if the base is oval and the stitching is tight.
- Pros: fast, clean inside, very durable.
- Cons: controlling the "straight" shape is more difficult; if the material is elastic, deformations must be monitored.
Option B: in pieces (panels + seam)
Ideal if you want a shopper bag with sharper corners and complete size control. Perfect for rectangular bags and premium finishes.
- Pros: straight shape, very controllable, great for centered motifs.
- Cons: It requires sewing (well) and aligning pieces.
Guidance measurements for a comfortable shopper
These measurements are a guide to ensure the bag is practical without being too large. Adapt them to your liking:
- Width: 32–38 cm
- Height: 26–32 cm
- Depth: 8–12 cm
If you want a "real" shopper (for everyday use, carrying things), it's best to go to a compact store and consider getting a lining.
Step by step: round shopper (base + walls)
1) Knit the (oval) base
An oval base is usually the most comfortable for a shopper. The idea is to knit in the round with increases until you reach the desired base size.
- Knit an initial chain according to the base length you are looking for.
- Work around the chain (go up one side, turn, go down the other side), increasing at the ends to form the oval.
- Repeat rounds until you reach the desired base width .
2) Mark the base/wall break
To make the bag rise without losing its shape, do a transition turn:
- Recommended option: one round catching only the back loop (BLO).
- Alternative: a round of slip stitch (loosely) for reinforcement.
3) Climb walls without increasing
From here, you normally knit without increases until you reach the desired height.
- Use lap start marker.
- Count your points from time to time: if you accidentally increase them, the bag will open.
4) Adjust the height and prepare the edge
When you are 2–3 cm from the final height, start thinking about the top finish: it's the perfect time to reinforce.
Step by step: shopper in pieces (panels + sewing)
1) Knit two identical panels (front and back)
- Knit a rectangle of the desired width and height.
- Repeat the same process (counting rows and stitches, not by eye).
2) Decide on the fund
You have two options:
- Flat bottom: sew the two panels together at the bottom and sides, and you're done.
- Background with base: you knit a rectangular/oval base and sew it to give volume and structure.
3) Sew with a resistant technique
For shoppers, it usually works very well:
- Crochet stitching (single stitch or slip stitch) for maximum strength, or
- Stitch with needle + second inside pass if it's going to be quite heavy.
Handles: options and how to reinforce them
The handles are the critical point of a shopper's bag. These are the most popular options:
Option 1: woven handles
- Beautiful, integrated and easy.
- Essential: very compact stitch + reinforcement at the anchor (several stitches).
Option 2: handles made of ribbon, faux leather or leather
- They give a very professional finish and distribute the weight.
- Ideal if you want the bag to not give way .
Option 3: chain + strap
It looks great on lighter shoppers or elegant tote bags. Make sure to reinforce the anchor points well.
Pro tip: If the shopper will be carrying weight, avoid anchoring the handles to a single point. Distribute the anchoring force across several points and reinforce it from the inside.
Top edge: how to prevent it from opening
A good top edge is what keeps the bag from losing its shape with use. Two simple options:
- 1–2 rounds of compact single crochet .
- 1 round of slip stitch (loosely) as a clean finish.
Lining: when it's appropriate and how it improves the bag
If you want a durable and "workhorse" shopper bag, the lining is your best ally:
- It prevents the fabric from stretching under weight.
- It protects the interior and improves the finish.
- It allows you to add a rigid base so that the bottom is flat.
Typical mistakes and solutions
It opens and undulates as it climbs walls
Solution: Check that you are not increasing and mark the base/wall break with BLO or firm transition.
The bag gives way under the weight.
Solution: more compact stitch + edge reinforcement and handles; consider lining.
The shopper is crooked
Solution: When sewing in pieces, align and mark corners before sewing; when sewing in the round, use a marker and check the start of the round.
The handles are deformed
Solution: reinforced anchoring (inside and out), or webbing/leather handles to distribute the load.
- T-shirt yarn and cord for bags with body and a clean finish.
- Accessories (handles, chains, clasps) for a more professional result.
- Markers, yarn needles and basic haberdashery supplies to finish things off nicely.
A stylish shopper bag isn't just about size: it's about a compact knit, a sturdy top edge, and well-reinforced handles. If you pay attention to these three elements, your bag will be comfortable, durable, and have that clean finish you'll want to use every day.
