A method of forming a wound fiber package comprises winding a first portion of strand having at least one fiber on a bobbin using a first indexing ratio A:B, wherein A is greater than 0 and A is greater than B, and winding a second portion of strand having at least one fiber on the bobbin using a second indexing ratio A:B different from the first indexing ratio, wherein A and B are greater than 0. In one non-limiting embodiment of the invention, B equals 0 in the first indexing ratio, A in the first indexing ratio equals A in the second indexing ratio, and A equals B in the second indexing ratio. In another non-limiting embodiment of the invention, B is greater than 0 in the first indexing ratio, A in the first indexing ratio equals A in the second indexing ratio, and A equals B in the second indexing ratio. This method may be used to produce a wound package.
