Basic Skills Necessary:

  • Techniques Used: knit, increasing/decreasing, casting on (cable CO and backwards loop methods), beading (crochet hook method).

Pattern Description:

This sideways-knit garter stitch shawl features an unusual tentacular edging and optional beads, and recalls Harry Potter's Venomous Tentacula, a green, spikey plant with mobile vines that grab living prey, aggressive shoots that expel venom, and a poisonous bite.
The sideways edging is made by repeatedly binding off and casting on stitches, creating a pattern of "holes."
Any yarn and any amount may be used; instructions are given for adjusting for different yardage.


Gauge: 24 stitches and 28 rows/4" in garter stitch, after blocking.

Sizing / Finished Measurements:

  • Size: 50" wingspan by 20" depth; edging is approximately 6" deep.


  • Yarn: Malabrigo Yarn Sock (100% merino wool; 440 yards), 1 skein Aguas.
  • Other Materials: US 6 24" circular needle, or size to match gauge. Yarn needle. Stitch marker (1). Size 1.15 mm crochet hook, for placing beads, optional. 120 size 6/0 seed beads, optional - this number will change if using more or less yardage
