Changes

New lengths of yarn must have been joined in at intervals but, as there are no loose ends visible, they must either have been joined by splicing or stitched into the fabric. As the work was continued round after round, shaping was added by working extra loops into the row below, or by missing a lower loop out. At the heel, the line of work has been turned back on itself several times to form the heel shaping. At the ankle it circles round a few more times until the last row, which is worked in a smooth dark yarn, dyed with madder (dye tests on the rest of the sock were negative). Because this technique does not unravel, no special finishing border is needed, and it is therefore uncertain whether this last row was a decorative edge or whether the sock continued in to a stocking with a red coloured leg.
