Crocheting for babies can be enjoyable, and it is a way to add custom pieces to a baby's wardrobe. Sizing for babies can be a challenge, though, as each baby's body is different. Because of this, sweaters and rompers can be a lot of work and might not fit the baby properly, or they might only fit for a short time. Ponchos are a way to sidestep the fit issue; they offer a one-size-fits-most opportunity for crocheters to make a customised baby garment.
Make 78 chain stitches. Create a chain stitch by tying a slip knot and placing it on the hook. Wrap the yarn around the hook's tip, and pull the hook's tip through the slip knot, forming a new loop of yarn. This is one chain stitch. Repeat this process until 78 chain stitches are made, not counting the slip knot as a stitch.
Make one double crochet stitch in the fourth chain stitch from the hook and in each chain stitch across. Turn the work so that the last stitch made is now facing as the next stitch to be worked. Make a double crochet stitch by wrapping the yarn around the hook's tip, inserting the hook through the indicated stitch, wrapping the yarn around the hook's tip again, and pulling a new loop through the stitch. Wrap the yarn around the hook's tip again, and draw the hook through two of the stitches on the hook. Wrap the yarn around the hook once more, drawing the hook through the remaining two loops on the hook.
Make three chain stitches. Make one double crochet stitch in each stitch across the row. Turn the work so that the last stitch worked is now facing as the next stitch to be worked.
Make three chain stitches. Make one double crochet stitch in each of the next four double crochet stitches; make two double crochet stitches in the fifth double crochet stitch. Repeat this pattern across the row. You will have increased 15 stitches by the end of the row. Turn the work.
Repeat Step 4 until the piece measures 11 inches from the beginning. Fasten off by cutting the yarn, leaving a 6-inch tail. Wrap the tail around the hook's tip and draw the hook through the last stitch, pulling tightly to secure.
Fold the poncho so that the edges are lined up, the narrower part of the work at the top and the wider end of the work at the bottom. The wider end is the end where you increased the stitches. Create a seam 6 inches long, working from the bottom of the work along the fold of the poncho. To make the seam, slip stitch the stitches together. To slip stitch, insert the hook through both stitches (one stitch on each side of the fold), wrap the yarn around the hook and draw the hook through both stitches.
Finish the poncho by sewing a button to one side of the poncho, 2 inches above the end of the seam created in Step 6. Weave the loose ends of the poncho into the work using the yarn needle, sewing a few stitches along the work's edge and then clipping any excess loose ends with the scissors.
Follow the care instructions on the yarn's label when washing the crocheted garment.
