It is starting to look nice, this sock... and I have decided to knit them up for Jouke. We discussed the foot size yesterday... his foot is 1 inch shorter than mine. But he was clear about his preference: rather a tiny bit bigger as he can grow into it... than perfect size and outgrown within a year or so. LOL!
The yarn, by the way is one I recently bought in Zoetermeer: Gründl Wolle Yale. It is a bit rough, compared to other sock yarns (less flexible), but for socks without patterns it works perfect. He will have warm feet when they are ready for sure.
