The Woobles kits use their own custom Easy Peasy Yarn , which is a worsted-weight (#4) t‑shirt/chainette-style tube yarn made from a 75% cotton, 25% nylon blend, designed so it doesn’t split and is easier for beginners to see their stitches.

What kind of yarn it is

  • Fiber content: 75% cotton, 25% nylon, marketed as “Easy Peasy Yarn.”
  • Weight: Worsted/medium #4 yarn, suitable for standard crochet hooks used in their kits.
  • Structure: T‑shirt/chainette “tube” style yarn (often compared to shoelace or tube yarn), which gives it a smooth, modern look and avoids splitting.

Why Woobles uses this yarn

  • Beginner friendly: The smooth tube construction means there are no separate plies to snag, so stitches are easier to see and count while learning.
  • Easy to work and “frog”: The cotton‑nylon blend holds shape but isn’t fuzzy, so pulling back (frogging) is simpler than with chenille or fluffy yarns.
  • Consistent look: It gives Woobles amigurumi that clean, slightly stretchy, athletic‑fabric style texture people associate with their kits.

If you want something similar

  • Use more Woobles Easy Peasy Yarn: They sell skeins of the same yarn separately (often labeled as “Beginner Yarn” or “Easy Peasy Yarn”).
  • Try other tube/t‑shirt yarns: Look for cotton/nylon tube yarns or “shoelace yarn” in a worsted/medium #4 thickness to get a similar feel and ease of use.
  • Regular substitutes: Any smooth worsted weight #4 yarn will technically work for making “woobles,” though the texture and look will be a bit different from the original kits.

TL;DR: When people ask “what kind of yarn does Woobles use,” the answer is their custom Easy Peasy Yarn: a 75% cotton, 25% nylon, worsted-weight t‑shirt/chainette tube yarn created specifically so beginners can crochet amigurumi without fighting splitty strands.
