Did you see the bobble stitch on that hemline? ADORBS. Simple raglan jumper dress and cardi, both with a wide rib and crew neck to keep those wee nippers nice and warm.
This was written for a (sadly) discontinued yarn but would look just lovely in King Cole Drifter Chunky. If you wanted to knit something a little more subtle, you could try out King Cole Drifter Subtle Chunky. It is a cotton, wool and acrylic blend that comes in solid colours with a bit of a marl to it that looks great.
These patterns are knitted on 5mm and 5.5mm knitting needles.
