This is a sweater for Kristel Kuslapuu’s collection Hero (more here). My name is mentioned in Estonian news (here).
In Estonian knitting tradition the stitch pattern is called maokiri (snake pattern), hence the name.
The yarn is extremely bulky, 100 g/100 m (Amalia, by some Bulgarian firm). I used 7.5 balls of orange, 4.5 balls of blue and about 1 ball of black and white each.
