This is a fun knit, my kids loved it. AND if you’re using worsted weight yarn, you’ll get a BIG DINOSAUR. (We’re talking 19”!)
I also used sport weight yarn (less than 100 yds!) and it turned out to be 10” tall.
However, if you use bigger/smaller needles and yarn will get you a bigger/smaller toy.

Let me know how you like the pattern, and please let me know if you have questions!
