I knitted the yarn in double and used just 3 balls of grey, it was a good idea to have one ball more because it was exactly 3 balls, at 5 grams…
With 3mm needles the stitch is dense but I like it for the winter, and it’s still not a huge sweater.

I made size 2 with length somewhere between 2 and 4 for my 3 yo son. It’s still too large but I’m not surprised : he still wears his 1,5 or 2 years t-shirts… It will be loose for this year, perfect next year and just fitted or still good the year after !

Very happy with this pattern, nothing to say : clear, easy to follow and a great result.
Maybe a little more explanations for the hem would be goog, I followed a how-to found on the web but the grey strand is visible on the orange hem, I didn’t know how to make it invisible.
