Opal Petticoat on size #0 DPNs (that's 2.0 mm)
Pattern is Lacy Scallop by Sockbug
I knit these on DPN's because I haven't got circs for socks. I tried magic loop method and don't like it but I haven't yet tried two circs. Maybe someday. For now I'm quite happy using DPNs.
On the final repeat before the cuff, I p2tog in the center of what will be the heel stitches so that I have 32 heel stitches instead of 33.
To knit the heel flap I did this:
row 1: *S1, K1* repeat to end
row 2: S1, purl across
row 3: S1, *S1, K1* to within one stitch of the end, K1
row 4: S1, purl across
For row 12 of the last pattern repeat on the foot preceeding the toe I did a knit row instead of a purl row.
For the toe, I knit as directed until 32 stitches remained and then decreased every row until 16 stitches remained and finally grafted closed.
