wavy scarf

I took a break from all the charity knitting I've been doing to make myself this Scarf. Of course, I couldn't stick to the pattern. I cast on with size 7's and did the first two increases with those needles but then switched to 9's when I did the last group of stitches. Also I did 4 rows of the first 120, then I did 5 rows of the 240 and 6 rows of the 480. I really like how it turned out. I didn't get it done in time for the party I was making it for, but I'm sure it will be worn and I'm going to make another in a sparkley white.
