This pattern utilizes both knitting and crochet techniques.
Description from Tangled:
The lovely crochet portion of this craft-combining garment reminds us of waving fronds of seaweed. Worked from the top down and completely seamless, it brings together various stitches from both knitting and crochet to form a simple yet stylish garment. Easy customizations make it possible to adapt the pattern for a wide range of body types. Wear it short like a top or work on to a tunic or even a dress length. Make a summer version with short sleeves or work them to elbow or wrist length for other seasons.
24 stitches and 28 rows = 4 inches in Stockinette stitch
I started very young. Basic knit sts taught by my Ma and crochet sts by my aunt. Beyond that I am mostly self-taught. Started designing straight away. My first project ever, being a boat-neck sweater for me. It was perfect!
