Whatever you call this item of crochet baby clothing - a baby grow, a baby onesie, a baby suit - one thing is for sure, they're going to look unbelievably cute in it! Made in super-soft 100% wool and featuring fab stripes in 3 shades, you'll enjoy hooking it up almost as much as baby will love wearing it. Crochet baby clothing is a relatively simple but incredibly thoughtful gift for new parents, and often become items that are held onto long after baby has grown out of it (or even better, they can be passed down)!

Notes

Onesie is made in 2 pieces for Right and Left sides, which are joined in the centre. Each piece is worked bottom up in rows for the Leg and continued straight to the armholes, where it is divided for Front and Back. Sleeves are made separately. The body pieces are joined first with a central Back Band, and bands are added to Back Leg edges and Right Front edge. A Buttonhole Band is worked along Front Left edge and a Neckband is added. Change colour in the last yrh of the previous st. Carry yarn up the side of the fabric.

For safety, it is important that all yarn ends are sewn in or crocheted over, and that buttons are attached firmly.
