Well, I thought I had it and typed it out but no!
So I drew a zig zag pattern upwards and wrote k, p on each line and decrease where indicated which may be the best way to do it but I can't do it on here.
However, carry on decreasing the raglan as before in every knit row but I think you will have to use a row counter to decrease on the front edge as follows:
Row one (Next Row in instructions) knit and decrease at front and raglan
Row two (Next Row in instructions): Purl
Row three: knit and decrease at raglan
Row four: Purl
Row five: knit and decrease at raglan
Row six: Purl and decrease at front (end of row)
Row seven: Knit and decrease at raglan
Row eight: Purl
Row nine: Knit and decrease at raglan
Row ten: Purl
Row eleven: Knit and decrease at front and raglan
Then continue, decreasing at raglan on every other row and decreasing at front edge on every fifth row.
Every other time the decrease on the front edge will be on a purl row.
If you include the first two instruction rows, that will be 32 rows altogether.
I think that's right, perhaps someone else may work it out differently
