Big Grauple monster comes out about 25cm, almost 10inch high. Gauge is not important, make sure though your needles are slightly smaller than indicated in your yarn. I used DK/worsted yarn, and a 5dpn set size 3mm needle, 2US needle. You will also need some colorful felt to finish arms and legs, and a big 3cm/1.25inch plastic eye. Enjoy and don’t forget to make little babies to big mama Grauple :)
