Free seamless cardigan knitting patterns (top-down & no seams!)

Let’s be honest: how many beautiful sweaters are hiding in your project baskets right now simply because they need to be seamed together? Seaming can feel like a tedious chore that stalls your creative momentum. That is exactly why seamless cardigan knitting patterns are a total game-changer.
When you choose a seamless design – usually knit from the top down – the garment grows organically on a single pair of circular needles. The absolute best part? You can try the cardigan on as you knit! If you want to check the shoulder fit or adjust the length, you just slide the stitches onto scrap yarn and slip it on.
Plus, without rigid, bulky side seams, the fabric drapes naturally over your curves for a comfortable fit.
Pro-Tip: Because you hold the entire body of the cardigan at once, always use a long circular needle (32″ or longer) to give your stitches room to breathe, even though you are knitting back and forth flat.

Expert Underarm Finishing Tip
When you separate your sleeves from the body, patterns have you cast on extra stitches to bridge the underarm gap. To avoid getting tiny gaps or holes when you return to knit the sleeves, try this: pick up one or two extra stitches in the deep corners of the underarm on your first round, and then knit them together (ssk or k2tog) with the neighboring stitches on the next round. This completely plugs the gap for a flawless finish!
