I actually got round to completing my latest socks yesterday evening. The yarn was from Hipknits, but was missing a label so I'm not sure of the fibre . However it is very soft and I would guess that it is Alpaca. To be honest, I'm not sure that they will stand up to hard wear so will probably be lounging-round-the-house socks.
The yarn was D.K. weight, needles size 3.25mm. knitted toe up with short row toe and heel, magic loop. The pattern, Single Eyelet Rib courtesy of Barbara Walker's First Treasury.
Finished with a Picot edge as a cast off edge would have been too tight.
