Single bed Roll Top Fair Isle sock on KH260.

I use either 3 strands of 2 ply lambswool or 2 strands of 4 ply, but they can also be done 1 strand of aran weight wool.

The socks in the picture are made using 2 strands of King Cole 4 ply anti tickle merino which I found worked best on tension 3, but I usually use tension 4 for 3 strands of 2 ply lambswool because it fluffs out.
