This design:
https://www.etsy.com/listing/1649157043/dragon-crochet-pa...

Held yarn double, 7.0 mm hook, because smaller hooks with this yarn double was hard on the hands.
Want to use the yarn up.
Didn’t want the finished stuffie to be super enormous.
The ravelry design page states that it is 48” long, but on Etsy, 24”.

(Next one, a hatchling, will hold yarn single str, 5.0 or 5.5 mm hook.)

From the designer:
If using blanket yarn and a 6mm hook it’s about 3 ft (36”) long or a little less.
With worsted weight about 1-1.5 ft (12 - 18”)

There were a couple typos in the directions and a couple places where I was confused but I contacted the designer and she replied promptly. She said she’d make the corrections and clarifications.
