The manufacturers' instructions that I have seen indicate that the side pocket rail folds be done with a relief cut almost up to the cushion nose. The mechanic in this video looks to get a good result by doing the fold without one (at about 5:30).

Is his method a good one, or will it leave too much cloth bulk in the fold?
