Acrylic Yarn: Projects, Blocking and Care
Acrylic is a manufactured synthetic fibre used in many easy-care yarns. Its important finishing difference is heat sensitivity: do not treat an acrylic project as though it were a wool piece that can be reshaped with steam.

Choose the care routine before the project
An item intended for frequent laundering needs a yarn whose stated wash and drying instructions suit that routine. Some acrylic products permit machine washing and drying, but a blend or a different construction may not. Keep the band with the finished gift instead of describing all acrylic as universally washable.
Leave steam out of the first experiment
Lion Brand advises against steam blocking acrylic because of its sensitivity to heat. Do not use direct ironing to force a finished piece into size. Start with the product’s permitted washing and shaping process on a spare sample, then assess the result once it is dry.
Blankets are fabric, not just yardage
For a large blanket, fold your sample into several layers and handle it as you would the finished object. Judge bulk, flexibility and the feel of the stitch against the intended use. A thick border can change those qualities even when the centre fabric feels right.
Replacing a wool blend
Matching thickness does not transfer wool’s felting or recovery behaviour to acrylic. Compare the original and substitute in the same stitch and washing routine. If the pattern relies on a deliberately felted finish, choose a yarn explicitly suited to felting rather than an acrylic replacement.
Try this before a full project
For a washable throw, make both its centre stitch and one corner of the border. Launder the sample within the label instructions and check the flatness, dimensions and edge before buying the full quantity.
