I took some liberties with the pattern.
First off I used german short rows instead of w&t

I used version 2 of the pattern as my basis but changed it as follows.

Color 1 (gray)
Knit one row
Row 1 (RS): knit
Row 2: knit
Row 3: knit
Row 4: p12, w&t, k8, w&t, p7, w&t, k6, w&t, p5, w&t, k4, w&t, p20, end last repeat p9
Row 5: knit, picking up and knitting the wraps as you meet them
Row 6: knit

Color 2 (green)
Row 7: knit
Row 8: knit
Row 9: knit
Row 10: p5, w&t, k5, turn, p4, w&t, k4, turn, p19, w&t, k8, w&t, p7, w&t, k6, w&t, p5, w&t, k4,
w&t, p20, end last repeat p16, then at end of row, turn, k5, w&t, p5, turn, k4, w&t, p4
Row 11: knit, picking up and knitting the wraps as you meet them
Row 12: knit

Repeat 1-6 using Color 3 (yellow) then 7-12 using Color 1 (gray) - 1-6 using Color 2 and 7-12 using Color 3

I ended with color 1 and bound off.
