Dancing Palms Shawl - a knitting pattern

At the end of last year I participated in Nautical Knitting Cruise. One of my tasks as a teacher was to create a shawl that was easy enough to knit on when you leave the classroom, fun to make and pretty. My Hubby offered to create two new colors especcialy for that shawl: Carribean Blue (which seriously looks like the Carribean waters!) and a speckled contrast named Jelly Fish.
I loved every stitch, the fun constuction which looks like an arrowlike shawl but in fact is not, and the colorplay created by the yarns.
Today I have the pleasure to release the pattern for you. Grab two contrasting skeins, cast on and watch the fun texture be born <3
