It is wonderful to see such beautifully colourful sweaters about at the moment, including this one called Simultaneous Sweater. The astonishing thing I find with this one, as someone fascinated by colours, is how your eyes deceive you into thinking there are more colours involved than just the 4 colours that are used in the pattern. Just looking at the orange band it looks like 2 shades of orange, but it is just one. Love, love LOVE it. I see this pattern in my future.
