I knit the child version on 3mm needles and added some length to the hand section, other than that followed the pattern as written.
This new yarn by Ovelha Negra, Amelia, is an absolute dream to work with, its 100% merino, super soft and holds up really well being ripped out several times (it took several times to get the fit right). Didn’t need to soak at all, and it’s even softer after blocking.
Colour used is no. 45, I call it a hunter green
