I used a DK weight yarn.
The pattern is , CAst on multiples of 12st
Knit 4 rows and then proceed.
Row 1-- Knit
Row2--Knit 4st,Purl to last 4 st.Knit 4st
row3--Knit 6,* k2tog twice,(yo k1)4 times,(K2tog)twice*RPT from * to * till last 6 st K6
Row 4-- Knit
Rpt rows 1-4 to desired length
Just go as long as you like and then knit 4 Rows before you cast off.
Hope this helps
