The Sloth from the pictures is made using Himalaya Dolphin Baby yarn (about 2 skeins of the main colour) and a 4.0mm size hook and to make the fingers I used thinner yarn (YarnArt Jeans) with 2.2mm hook. Of course you can use any yarn with similar weight, just remember that the second yarn for fingers has to be thinner than the main yarn. My plushie, made with mentioned yarns is about 28cm (11 inches) high sitting (head and body).

The pattern is meant for beginners and intermediate crocheters.
