It's a great pattern, once you get it started it crochets up very quickly...to be honest, I couldn't put it down. I loved seeing the colours come through as I went along, you can purchase the pattern here....I love it!
This is what I'm playing with now..knitted in 8 ply wool, really easy to do , twists and ruffles up as you go..
With 8 ply yarn
Cast on 23 sts.
Row 1...knit 2 turn and knit back on those 2
Row 2...knit 4 turn and knit back those 4 sts
Row 3...knit 6 turn, knit back those 6
Row 4... knit 8 turn, knit back those 8
Row 5...knit 10 turn, knit back those 10 sts..
Row 6...Knit right across all 23 sts to come to the other end...
Repeat these 6 rows at this other end...and then repeat these rows again on opposite sides...
This forms a twisted ruffle as you work up..thought you might like to try it..I'm just using what I have on hand...but wouldn't it look great in a variegated coloured yarn..
