What Is Acrylic Yarn and Why Do Makers Choose It?

If you’ve ever looked at a handmade crochet item and wondered what it’s made from, or if you’re someone who pays attention to whether the things you buy are vegan-friendly, this post is for you. At Blue Belle Charms, I use 100% acrylic Women’s Institute yarn for every single piece I make, and that’s a deliberate choice with some really good reasons behind it.

So what actually is acrylic yarn?

Acrylic yarn is a synthetic fibre made from a polymer called polyacrylonitrile. In plain English: it’s a man-made fibre, not a natural one. It was developed in the mid-twentieth century as an alternative to natural fibres like wool and cotton, and it’s now one of the most widely used yarns in the world, for very good reasons.

Unlike wool, acrylic yarn contains no animal products whatsoever. It’s made entirely from synthetic materials, which means it’s 100% vegan-friendly. It also doesn’t felt (the process where wool fibres lock together and shrink irreversibly when washed), it’s resistant to moths, and it’s generally much easier to care for than natural fibres.

Is acrylic yarn vegan?

Yes completely. Acrylic yarn contains no wool, no alpaca, no mohair, no silk, and no other animal-derived fibres. It’s entirely synthetic. This makes it an excellent choice for makers who want to ensure their products are suitable for vegan customers, and for shoppers who prefer to avoid animal products in the things they buy.

At Blue Belle Charms, this matters to me. I wanted to make a shop where everyone can buy with confidence, regardless of their approach to animal products. Using 100% acrylic yarn means every single piece I make, every bookmark, book cover, car charm, coaster, pouch, and scrunchie is completely vegan-friendly without exception.

Acrylic yarn vs wool: what’s the difference?

Wool is a natural fibre with a wonderful warmth and softness, and it’s a great choice for many things. But for the kind of handmade gifts and accessories I make at Blue Belle Charms, acrylic has some really significant practical advantages:

• Durability: Acrylic yarn is extremely hard-wearing and holds its shape well with regular use. Wool can pill and wear more quickly, particularly in high-contact items like bookmarks and coasters.
• Colourfastness: acrylic yarn holds dye exceptionally well, which means the colours stay vivid wash after wash. It’s one of the reasons handmade acrylic pieces look just as good after a year of use as they did when they were new.
• Washability: Acrylic yarn is much more forgiving in the wash than wool. Wool can be felt and shrink if it gets too warm or is handled roughly; acrylic handles gentle washing with ease.
• Vegan credentials: Wool requires shearing sheep, which not everyone is comfortable with. Acrylic has no animal involvement at any stage of production.
• Accessibility: Acrylic yarn is widely available in a huge range of colours and weights, which means makers can produce consistent, colourful work across a full range of products.

Why Women’s Institute yarn specifically?

There are lots of acrylic yarns on the market, and I’ve tried a fair number of them. I use Women’s Institute yarn for everything at Blue Belle Charms because the quality and consistency is genuinely excellent. It has a structure that works beautifully for the pieces I make — firm enough that bookmarks hold their shape and book covers protect properly, soft enough that scrunchies and pouches feel lovely to hold. The colour range is wonderful, and the colours are reliable batch to batch, which matters when I’m making coordinating sets.

It’s also a trusted British brand with a long history, and there’s something that feels right about using it for handmade pieces that are themselves made in the UK. It’s not a detail I’d thought about consciously until someone asked me about it at a craft fair, but once I did think about it, I was glad it was the case.

Is acrylic yarn sustainable?

This is a fair question and one worth answering honestly. Acrylic yarn is a synthetic, petroleum-derived product, which means it’s not biodegradable in the way that natural fibres are. It’s also worth knowing that synthetic textiles can shed microplastics when washed, though this is significantly reduced by washing at lower temperatures and using a mesh laundry bag.

The honest answer is that no yarn is perfectly sustainable; natural fibres have their own environmental considerations, including land use, water consumption, and animal welfare. What I can say is that the pieces I make are built to last. A well-cared-for acrylic crochet piece will look good for years, which is the opposite of fast fashion. Buying something handmade and keeping it for a long time is one of the most sustainable choices you can make, whatever the fibre.

Can acrylic yarn cause allergies?

One of the significant advantages of acrylic yarn for people with sensitivities is that it contains no animal proteins, which means it’s generally very well tolerated by people who have wool allergies or sensitivities to natural fibres. If you or someone you’re buying for has a wool allergy, acrylic is typically a safe and comfortable alternative. As always, if you have a specific or severe allergy, it’s worth checking the full fibre content before purchasing.

The short version

Acrylic yarn is a synthetic, vegan-friendly fibre that’s durable, colourfast, easy to care for, and excellent for handmade gifts and accessories. It’s the reason the pieces at Blue Belle Charms hold their shape, stay vivid, and last — and it’s the reason every single item in the shop is suitable for vegan shoppers. If you’ve got questions about any of the pieces or the materials, I’m always happy to chat.
