Small amount of worsted weight yarn in the house colors of your choice
US 6 (4.00 mm) DPNs
G/6 (4.00 mm) crochet hook
3.75" x 1.5" (9.53 cm x 3.81 cm)
Cast on 18 sts using your main color (MC) and a tubular cast on.

Change to CC and knit another 2 rounds in stockinette st.
Change to MC and continue to knit around until the sock is 2" (5.08 cm) long.
With CC, work a short row heel on 9 sts, using the short row wrap.
Work the short rows for 4 rounds or until there are 5 unwrapped stitches remaining.
Once the heel is done, work a scant 1" (2.54 cm) of instep in MC.
Work 1 round in CC and then begin short row toe as for heel.
Using about a foot (30.48 cm) of yarn, graft the toe to the instep.

If the first tail isn't in the middle back of the sock, weave it in until it is.
Crochet chain 7 sts with the crochet hook and pull the tail through.
