The layout is similar to a bargellow with fracture strips.
How wide are the solid (a, c, etc) stripes?
How wide are the dark strips within the light stripes?
You could measure the "offset" and mark the strips accordingly then attach.
If it were me I would try to first use a ruler with both a straight edge and a diagonal - with the diagonal line matching the same angle as your strips (ie 30, 45) - hopefully the stripes in the striped strip set (say that fast three times) are an equal and easy to measure angle.
Once you know the angle, you can use your straight edge along the solid line of the solid strip and mark the angle with the offset of the strip width.
Not sure if that is making sense .....
