Acrylic is a synthetic fiber spun to imitate wool. It is inexpensive, widely available, hypoallergenic, and almost always machine washable and dryable, which is exactly why it dominates beginner kits, baby blankets, and charity projects. If you frog and redo a project several times while learning, acrylic costs little and survives the handling.
The trade-offs are real. Acrylic does not breathe like natural fibers, it can pill with wear, and it does not block the way wool does, so a steam or wet block relaxes it only a little. It also melts rather than singeing under high heat, which makes it a poor choice for potholders and trivets where cotton is far safer. For warmth, washability, and price, though, it is hard to beat.
Quick reference
- Care
- Machine wash and dry on low. Never use acrylic for potholders or trivets, since it melts under heat.
