I used the same knitting pattern as for the baby cable hat, increasing two stitches on each needle on the last ribbing round so that that there are 18 stitches on each and the same booties, increasing just one stitch (18 stitches) on the first row of the pattern and substituting this lace pattern for the cable pattern:
(9 stitches, 4 rounds)
Round 1 K2togb, yo, K3, yo, K2togf, P2
Even rows K7, P2
Round 3 K2 yo, sl1, K2 tog, psso, yo, K2, P2
