I have an entire Jacobs Crackers tin full of buttons and yet couldn't find three suitable buttons to finish off this cardigan.
Following a pattern for a 6 month size but with any old DK instead of the recommended brand resulted in a size suitable for a nearly two year old. Lesson learned. Luckily this was with foster children in mind and my sister in law fosters children up to three years old. Phew.
I'm going to attempt another baby cardigan next, excuse me while I go and work up a tension swatch!
