No fuss and no frills, our free Little Baby Sweater knitting pattern is a wonderfully simple striped cardigan designed just for that fleeting newborn moment. We’ve updated this beloved pattern so you can knit it in Quartz, our radiant merino wool and suri alpaca yarn… Sumptuously soft and very special!

Just right for that soft little newborn shape, this darling pattern comes in just one size that will fit most brand-new babies for those special first few months. Knit all in garter stitch, with no shaping and very little sewing, you knit the body from the bottom up in one piece, binding off stitches for the underarm to leave a square little hole for each sleeve. Those clever-yet-easy inset sleeves are picked up and knit sideways, with just the tiniest seams under the arms… Easy and straightforward!

We made the button bands as easy as they can possibly be, too. You actually knit buttonholes on both sides, and then simply sew the buttons over one of the two sides. That means they’ll be placed perfectly every time!

Our Quartz yarn makes this project joyful to knit, beautiful to look at, and so soft and comfy for a new baby to wear. A wonderful mix of 65% merino wool and 35% suri alpaca, this fingering-weight yarn has a subtle halo and a lustrous, lit-from-within quality to every color. Pick two from a palette of very inspiring colors… You only need one skein of each, and you’ll have enough left over to knit another sweater with the colors reversed!
