I really want to make this but I don't want to shell out lots of money for the Twinkle yarn and have no idea what to use as a sub.
The Twinkle cruise yarn is a dk weight yarn so I just subbed some dk weight from my LYS that was reasonably priced. My guage was the same.
purple stitches -- can't wait to see what yours looks like sounds like a good color choice. I went with a light gray with silver strands mixed in. liking it so far.
