Pattern: Neat Ripple Pattern, from Lucy at Attic24 (here)
Very easy after a few rows and almost no ends to weave in as it can be done as you join a new colour.
I love that blanket and the colours are so beautiful. After playing with my colour pegs for hours (I found that idea on Lucy's blog again... genius!), I asked Mr what he would pick and his first attempt was better than all of mine... thank you P, you saved the day!
