These socks are knitted from the toe up, using a provisional cast-on, so there is no need to graft the toes. The instructions for a provisional cast-on are in the pattern.
Soliloquy Sock Lace is a fine, high-twist 4-ply yarn, strong enough to knit socks with but much finer than most 4-ply sock yarns; Soliloquy = 600m per 100gr instead of the traditional 350-400m per 100gr.
Note: to achieve a firm fabric, the socks are knitted using 2mm needles.
