(J) requires a rapid increase, therefore the fashioning area (W2) may consist of 9 widening steps, each of which gives 2 edge loops at intervals of 3 courses, so as to produce a nice round heel. It is advisable to add further widenings at less frequent intervals, so that the edge between (J) and (K) in the area (W3) is rounded. This can be improved by adding 1 widening at both (J) and (K) at intervals of 10 courses. After the point (L) is reached, straight courses are knitted to (M).
For the formation of the bottom of the heel, the stocking blank is now reduced in width by about 14 narrowing steps, each giving a reduction of 2 loops each side between (M) and (N) in the area (Nl). Area (N2) (NO) is reached, and the fashioned instep narrowing is so arranged that this area should progressively diminish in width, so as to be narrower at the sole end than at the lower heel end.
The course frequency of narrowing the instep in the area (N2) may consist of 10 narrowings at intervals of l0 courses this depending entirely upon the weight of the fabric used, consistent with its elasticity. After the completion of this tapering instep, the knitting of the main portion of the foot is carried out in the usual way, and this, with a fashioned toe, completes the stocking blank. As there is a continuous selvedge edge round the heel, a single seam is used from top to toe of stocking.
