First of all, I'm loving how thick the cuffs are on the front cover sweater. Gorgeous and funky. They've styled it kinda sailor-y, and I'm loving the vibe! An easy knit jumper and cardigan, raglan shaping, from kids to adult size, all in a yarn that has a massive colour range. Plus, because it's just plain stocking stitch, it's pretty infinitely customizable if you're of the more intermediate-advanced knitter type. Nice!
This has been written in King Cole Pricewise DK, a 100% acrylic workhorse yarn with a massive range of colours. However, this pattern would work in any yarn, really. May I suggest the Riot DK for it's warmth and crazy shades?
You'll need 3.75mm and 4mm needles.
