Ainur Berkimbay has a gift for turning clever construction into something completely irresistible, and her Pinwheel Baby Romper is no exception.

• Aside from the baby wearing it, the highlight here is the pinwheel, a whimsical bib that evokes a whirligig in the breeze, a sand dollar on the beach, or a sweet William blossom in the garden. The pinwheel is also where you begin knitting, casting on just a few stitches at the center and knitting outward in the round, increasing at five points to create that distinctive shape. Then you get to do it all again to make an identical pinwheel for the back!

• Once the two pinwheels are complete, you join them across the underarms and continue downward in the round, shaping the hips and gusset into an irresistibly voluminous puffball. Attached I-cords at the armholes become delicate straps that tie at the shoulders, allowing for an adjustable fit as the baby grows.

• Incredibly soft and easy to care for, Stormy Superwash Sock is perfectly suited for a baby garment that’s sure to be worn and loved again and again. This fingering-weight yarn is made from 85% fine superwash merino wool and 15% recycled nylon, with a smooth surface and gentle bounce that makes it a joy to knit. It’s plenty soft and comfortable enough for babies—and since it’s machine wash- and dry-able, it’s as practical as it is beautiful.

• You’ll need just 2–3 balls of Stormy Superwash Sock to make a Pinwheel Baby Romper for a very lucky little one, in sizes from 3 to 18 months!
