Yarn for Crochet Bags: The Complete Guide to Choosing the Right Yarn

📖 7 minute read

Choosing the right yarn is the most important decision when crocheting a bag. More than the pattern, more than the hook, more than your experience: it's the yarn that determines whether the bag will be structured or soft, luxurious or casual, summery or wintry, light or heavy. And it's also the factor that makes the difference between a bag that lasts for years and one that loses its shape after just a few weeks of use.

In this comprehensive guide, you'll find the 6 yarn families we use at Macrè Bag, the criteria for understanding which one is right for your project, and links to all the in-depth blog articles. It's designed for both beginners making their first bag and those who want a reference to consult before each new project.

Why yarn matters more than anything else

A crocheted bag needs to hold three things: shape, weight, and time. Shape means it shouldn't lose its form when you put your belongings inside. Weight means it must be able to hold keys, a wallet, a phone, maybe a book. Time means that after a year, it should still look good, not faded or crumpled.

These three requirements depend 90% on the yarn. Yarn that is too soft (e.g., fine wool) results in "sac-like" bags that quickly deform. Yarn that is too rigid can be uncomfortable to work with and create "cardboard-like" bags. The right compromise exists, and it varies depending on the type of bag you want to make.

The 6 yarn families for bags

1. Cordino (Cord)

This is the classic "bag yarn" par excellence. Made of cotton (sometimes with a polyester core), it comes as a solid or hollow tube, generally 4-5 mm thick. Its main characteristic is its structure: cord gives bags exceptional hold, maintaining their shape even when full.

When to use it: Structured, elegant, city bags. Medium-large tote bags, bucket bags, shoppers. It's the ideal yarn for those who want a bag that "looks like it was bought in a store."

Pros: Perfect shape retention, elegant and neat look, wide color range, durability over the years.

Cons: Less suitable for beginners (requires a firm hand and some practice), bags are heavier compared to other yarns.

2. Pandorino

Pandorino is the yarn we recommend for those making their first bag. It's a twisted cotton, soft to the touch, generally thinner than cord but still well-structured. It's easy to work with even for beginners because it forgives small tension errors.

When to use it: First bags, mini bags, clutches, medium-structured "everyday" bags.

Pros: Easy to work with, excellent quality/result ratio, low weight, washable.

Cons: Intermediate structure (if you want a very rigid bag, choose cord).

3. Fettuccia (T-shirt yarn, lycra tape yarn)

Fettuccia is a fabric strip, generally 5-8 mm wide, which is crocheted as if it were a flat yarn. Pizza fettuccia (cotton) has a summery and light look, while lycra fettuccia adds elasticity and a slight satin effect.

When to use it: Summer bags, beach bags, light and airy models. Perfect for bags that "flatten" when empty (like a pouch).

Pros: Fast to work with (the tape is wide and covers a lot with each stitch), summery look, very light, easy to wash.

Cons: Less structured than cord, less suitable for rigid or elegant city bags.

4. Raffia

Raffia is the natural yarn par excellence, made from palm fiber. It comes as a flat, rough thread, typically straw-colored (though dyed versions exist). Raffia is lightweight, breathable, and has an immediate "beach vacation" look.

When to use it: Summer bags, beach bags, matching hats, beach accessories.

Pros: Extremely lightweight, iconic summer look, natural and biodegradable.

Cons: Rough to the touch during working, not suitable for bags used all year round.

5. Marshmallow

Marshmallow is one of the newest and trendiest yarns: it's an ultra-soft and voluminous tape yarn, 2-3 cm wide. Working with a large hook (size 12-15) results in very soft and roomy bags quickly.

When to use it: Autumn-winter bags, oversized models, soft bucket bags, bags to wear with coats.

Pros: Very fast to work with (a few hours for a bag), soft and modern look, reduced weight relative to volume.

Cons: Less structured, bags tend to deform if overloaded.

6. Magic Cotton

Magic cotton is our exclusive: a variegated twisted cotton that changes color along the ball, creating unique and unrepeatable chromatic effects. Each ball is slightly different, giving each bag a unique character.

When to use it: Statement bags, special gifts, artistic mini bags, "one-of-a-kind" accessories.

Pros: Unique chromatic effects, excellent visual appeal, pleasant to work with.

Cons: Less predictable (you don't know exactly how the color will turn out until the end), slightly higher cost.

How to choose the right yarn for your project

Now that you know the 6 families, I suggest three questions to help you narrow down your choice:

1. What season? Summer → fettuccia / raffia. Autumn-winter → marshmallow / cordino. Mid-season → pandorino / magic cotton.
2. How skilled am I? First time → pandorino. Good hand → cordino / fettuccia. Experienced → anything.
3. How much time do I have? A few days → marshmallow (quick to work with) / fettuccia. Weeks of time → cordino / magic cotton.

How much yarn do you really need?

One of the most frequent questions — and one of the main causes of projects abandoned halfway. Underestimating yarn means risking running out of the exact color halfway through the bag, and different dye lots never match 100%.

Practical rule: always buy 20% more than the theoretical requirement. For a precise calculation based on bag size, stitch type, and yarn, refer to the dedicated guide: How much yarn do you need to crochet a bag? Practical guide.

OEKO-TEX: why you care even if you don't know it

All Macrè Bag yarns are OEKO-TEX Standard 100 certified. You've probably seen this word on clothing or bed linen labels, but you might not know exactly what it guarantees.

OEKO-TEX Standard 100 is an international certification that verifies the absence of harmful substances in the finished product: heavy metals, pesticide residues, azo dyes, formaldehyde, and other dangerous compounds. It's particularly important for crochet yarns because:

• Hands are in direct and prolonged contact with the yarn for many hours
• Bag yarns often pass near the face (in shoulder bags)
• Sensitive or allergic individuals have an extra guarantee

Common mistakes in yarn selection

Over the years, working with many students and customers, I've almost always seen the same 5 mistakes recur:

1. Choosing a yarn that is too thin for the first bag. Fine cotton requires more hours, more stitches, more precision. To start, go for medium-thick yarns (pandorino, fettuccia).
2. Buying less yarn than necessary. As we said, always +20% of the theoretical requirement.
3. Not checking the dye lot. If you need to buy multiple balls of the same color, take them all from the same lot. Different lots can have slightly different shades, and it will be noticeable in the finished bag.
4. Ignoring the weight of the yarn. An empty cordino bag can weigh 300-400g. Add keys and a wallet, and you're up to a kilo on your shoulder. For daily use, consider this.
5. Mixing incompatible yarns. You can mix them, but it requires experience. For initial projects, use a single yarn.
