This is a smaller version of Diplodocus dinosaur stacking toy. This mini version of a toy takes much less time to make, comparing to original Diplodocus stacking toy. Also you may choose bulky yarn and larger hook and your plush will still have a reasonable size.
Did I mention already that you can finish it so much faster, not giving up on it’s cuteness?

Yarn: I used mostly “Alize cotton gold” yarn.
