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.”

Pattern is also available through Tangled Online Magazine.
