The third yarn I used was ~50g of a heavy fingering weight MCN that I hand dyed in variegated blue shades - similar to the Burnished Sport in Weathered Denim, but a little brighter.

Toe up with:

• spiral toe
• helix stripes in three colours
• riverbed gusset increases under foot
• Fish Lips Kiss heel
• 2x2 ribbing
• Elastic bind off

For comparison, I usually knit stockinette socks in standard sock weight yarn with 64-66 stitches in the foot, these have 54 and are a good fit.
