I knit these while travelling in Argentina, hence the name. I wanted an easy knit, but no boring plain vanilla, so I made up my own. Please find my notes below.

Row 1: knit all stitches
Row 2: p1, k3 repeat between **

56 rows
Start shaping of mini gusset: kfb at each end of sole stitches every 3rd row 4 times -> 69 rows and 36 sole stitches
