thanks - it's the right pattern. i've just worked it out. once you have finished the main body of the sweater you have two front parts left on stitch holders, which the pattern says to knit across, cast on, then knit across the rest (forming the hood). by doing this i've basically made the hood in reverse! i think the pattern is misleading as the only way to get the hood the right way round is to actually pearl across, then cast on, then pearl again. guess i'll have to undo and start again!
