I bought three different types and settled on the first choice in the end anyway. The colour's a bit weird in that photo up there, but in real life the combo works. No, really it does.
OK, ready to cast on the next one. I think I'm going to buy some Bendy wool this time...to match the buttons of course. I've got another nephew/neice arriving in January so I can now knit a cardy to go with the remaining buttons.
