1. A method of reinforcing a seam, comprising:
positioning two edges of flexible material together to form a seam allowance and positioning a first row of stitching on the seam allowance spaced from a body formed by the flexible material;
folding the seam allowance into a series of accordion folds to form the seam allowance into a series of parallel reinforcement layers, with the reinforcement layers being of similar size and forming a ridge;
positioning a ridge cap of the flexible material over the ridge, with the ridge cap providing at least one further parallel reinforcement layer of the series of parallel reinforcement layers; and
securing the ridge cap and parallel reinforcement layers together with further rows of stitching positioned between the first row of stitching and the body, with the stitching extending through all of the parallel reinforcement layers,, wherein the series of accordion folds comprises:
a first accordion fold oriented in a first direction and forming a first reinforcement layer of the series of parallel reinforcement layers, the first reinforcement layer being secured parallel to the seam allowance by a second row of stitching, a second accordion fold oriented in a second direction and forming a second reinforcement layer of the series of parallel reinforcement layers, the second reinforcement layer being secured parallel to the first reinforcement layer and the seam allowance by a third row of stitching, and, wherein a remote end of the seam allowance is folded over the ridge and oriented in the first direction to serve as the ridge cap, while forming a third reinforcement layer of the series of parallel reinforcement layers, the third reinforcement layer being secured by at least one of the third row of stitching or a fourth row of stitching.
