1. A method of making a blade for a wind turbine rotor, the method comprising:
manufacturing a pre-fabricated structure comprising a primary structure, an inner fabric layer, and an outer fabric layer;
transporting the pre-fabricated structure to a wind turbine site; and
injecting a filler material between the inner fabric layer and the outer fabric layer; wherein:
the inner fabric layer comprises a first edge and a first length,
the outer fabric layer comprises a second edge and a second length,
the manufacturing comprises applying a resin to the primary structure, the first edge, and the second edge, and
the manufacturing comprises protecting the first length and the second length from the resin.
