You can knit this pattern either with doubleknit wool and needles Size 2.5 mm, or four-ply wool and 2.0 mm needles.
I have mine as a decoration in my bathroom.
If you knit one-piece you can make a curved shell, which you could use as a small dish.
Two shells sewn together will make a small toy. Or you could put lavender inside to use as a clothes freshener.
My pattern explains how to knit either the plain or striped version.
