Choosing the right yarn for an amigurumi project can make the difference between a plushie that holds its crisp shape for years and one that feels floppy or sheds fiberfill. Here is our comprehensive comparison of the two most popular fibers for crochet toys.

1. 100% Cotton & Cotton Blends (The Gold Standard)

Cotton (such as DK weight or Worsted #4) is loved by amigurumi designers worldwide because of its unmatched stitch definition. Because cotton fibers have minimal stretch, every single crochet stitch sits crisp and neat.

  • Pros: Crisp stitch definition, zero pilling, durable for toys given to toddlers, easy to photograph.
  • Cons: Stiff on hands during long crochet sessions; splitting can occur with low-twist varieties.
  • Recommended Weight: Sport (#2) or DK (#3) with a 2.5mm to 3.0mm hook.

2. 100% Premium Acrylic (Soft & Forgiving)

High-quality acrylic yarns are soft, affordable, and available in hundreds of vibrant colors. They are gentler on beginner wrists and have slight give that makes tight stitches easier to work.

  • Pros: Budget-friendly, vast color palettes, soft and squishy feel, easy on hands.
  • Cons: Can pill with heavy friction; slight fuzziness can obscure micro-details.
  • Recommended Weight: Worsted (#4) with a 3.25mm or 3.5mm hook.
