What lightweight T-shirt yarn is and how it is made

T-shirt yarn is recycled textile yarn made from surplus materials from the fashion industry. These fabrics are cut into strips about 2–3 cm wide and then wound into balls ready to use. It is mainly used with large crochet hooks (8 mm to 12 mm) or by hand, in XXL crochet techniques.

Classic cotton T-shirt yarn is fairly heavy because it comes from thick, compact fabrics. This gives it substance, but it also means that a large rug can be difficult to move or wash.

In contrast, lightweight T-shirt yarn is made from selected materials that significantly reduce its weight without sacrificing strength or flexibility. It is much more comfortable to work with on large projects, as it allows you to create voluminous pieces without the project becoming a burden.

When to use classic cotton trapillo

Classic trapillo is still very useful in certain cases:

• Baskets and storage boxes: their firmness helps them keep their sides straight.
• Small or medium rugs: the extra weight prevents them from slipping.
• Small bags: it gives them body so they do not become floppy.
• Decorative projects that need structure: such as firm poufs or structured accessories.

When to use lightweight trapillo

Lightweight trapillo is the best choice for large projects or when you prioritize comfort:

• Large rugs (more than 80 cm in diameter or length): they are much easier to move and wash.
• Medium and large bags: since we carry them over our shoulder for long periods, lightweight trapillo keeps them comfortable to carry.
• Blankets, poufs or cushions: they allow you to crochet large pieces without the weight becoming a problem.
• XXL crafts: from headboards to hanging organizers, where lightness and volume are needed at the same time.

Which hook to use for lightweight trapillo

The recommended hook size depends both on the thickness of the trapillo and on your hand tension:

• Fine lightweight trapillo: 8–9 mm hooks.
• Medium lightweight trapillo: 10 mm hooks.
• Wider lightweight trapillo: 12 mm hooks.

👉 Tip: if you crochet very tightly, choose a hook one size larger so the project remains flexible. If you crochet very loosely, go down one size to give it more structure.
