🧵 The yarn

The Greenwool Eco-Wool from the Tre Sfere collection is a yarn designed for those looking for a sustainable product without sacrificing practicality. Made with 90% recycled acrylic and 10% other fibers, this yarn is a responsible choice for knitting and crochet projects. The natural melange effect makes every garment unique, with color variations that develop spontaneously as you work.

Each ball weighs 100 grams and provides approximately 310 meters of yarn, a generous yield that allows for medium-sized projects using only a few balls. It can be worked with 3–3.5 mm needles or a 3–3.5 mm crochet hook, resulting in a soft and compact fabric suitable for both winter garments and decorative accessories.

🧬 Technical composition: why it works

The heart of this yarn is recycled acrylic, a synthetic fiber obtained from recovered textile materials that would otherwise end up in landfills. This production process drastically reduces resource consumption compared to virgin acrylic, while maintaining the same characteristics of strength, elasticity, and ease of care. Recycled acrylic does not felt, does not shrink, and maintains its shape over time, making it ideal for garments meant to last.

The 10% of other natural fibers in the composition adds to the softness and breathability of the finished fabric. This small percentage balances the synthetic component, making the yarn more comfortable against the skin and enhancing the visual appeal of the melange effect. The result is an eco-friendly yarn that combines environmental sustainability with high technical performance.

📦 Ball format and yield

With 100 grams and 310 meters of length, this yarn offers excellent yield. A single ball is enough to make a medium-length scarf (approx. 150 cm), while a women's size M sweater requires about 3–4 balls, depending on the pattern and desired fit. The reference gauge is 10 cm = 19 stitches x 24 rows in stockinette stitch using 3.5 mm needles.

For larger projects like blankets or oversized cardigans, we recommend purchasing all necessary yarn at once, preferably from the same dye lot. The melange effect may vary slightly between different lots, and having balls from the same dye batch ensures color uniformity in the finished garment.

🧶 Recommended working methods

3–3.5 mm needles are the ideal size for this yarn as they create a fabric that is compact yet flexible, with good stitch definition. Smaller needles would make the fabric too dense and stiff, while larger needles would create a fabric that is too open and does not retain heat well. The 3.5 mm size is perfect for stockinette and lace stitches, while 3 mm is recommended for ribs and edges that need to hold their shape.

With a 3–3.5 mm crochet hook, this yarn is excellent for amigurumi, bags, granny blankets, and decorative accessories. The melange effect enhances simple stitches like single or double crochet, creating natural color play without needing to switch yarns. It is also suitable for beginners due to its smooth texture and strength, which is forgiving of minor tension errors.

✨ Why choose Greenwool Eco-Wool

Compared to traditional acrylic yarns, Greenwool resolves the issue of environmental impact without compromising on performance. Many synthetic yarns require large amounts of oil and water for production, whereas this one uses pre-existing materials, reducing textile waste. It is not a "second-rate" yarn: the quality of the recycled acrylic is identical to that of virgin acrylic, but with a much lower ecological footprint.

In daily life, this means garments that you can machine wash without worrying about shrinking or felting, that retain their color over time, and do not require special care. It is the right choice if you want to make children's sweaters that must withstand frequent washing, or blankets meant to last for years without losing their softness.

🎨 What you can make

This yarn is perfect for sweaters and cardigans to wear in autumn and winter, thanks to the acrylic's ability to retain heat. It is also suitable for scarves, hats, and gloves that need to withstand daily use and frequent washing. For the home, it is ideal for granny square blankets, sofa throws, and decorative cushions where the melange effect creates visual depth without needing to manage color changes.

👩‍🎨 Who is this for?

It is a yarn suitable for both beginners and experts. The smooth texture of the acrylic makes it easy to maintain consistent tension, and the durability of the yarn is forgiving of minor mistakes. Stitches are well-defined thanks to the regular twist, making it perfect for learning new techniques without frustration.

It is typically chosen by hobbyists looking for a sustainable yarn for everyday projects, moms who make children's clothing that requires frequent washing, and artisans who sell on Etsy or at markets and want to offer products with a credible ecological story. It is also highly sought after by those working for charitable associations, as the price-quality ratio allows for many garments to be made on limited budgets.
