A lot really depends on the print. Usually, whenever I am working with an obvious directional print in a border, I do cut it so the print is all in the same direction. I also buy to ensure that. Normally I would buy enough fabric to take my WOF cuts and then have enough left to cut two continuous LOF cuts so the printed design is in the same direction. If I don't have enough fabric, I cut my WOF first then put a seam in my LOF pieces. But I have had directional prints where it did look better to cut all 4 sides WOF and attached to the quilt in such a way that when the sides hang over the sides of the bed the directional print is right side up as viewer looks at it when viewing the bed from the side.
