knitted channelled wrack seaweed

This type of seaweed has flat fronds that curl up lengthwise to make a groove on one side. The fronds are greenish brown when wet and darker when they dry.

A printable version of this pattern is available.

You will need:

  • double knit in greens/browns/blacks

Needle/Yarn Size

As with most ODDknit patterns the yarn and needle sizes in the "you will need" section are just a guide. Feel free to improvise with whatever needles and yarn you have lying around - that's half the fun!
