Instant stripes

I started this jumper on the 20th August. Based slightly on the red & white striped boat neck top that is taking forever to knit.
I'm using a mercerised 4-ply cotton that I've had for ages. Originally I was going to do the whole sweater in red and white stripes, then I thought it would be more fun if the body was a different colour. Shades of those Artwork sweaters in the 80's.
