Trawling (appropriate for fisherman sweater, no?) through denim yarn patterns, I think I've found what my ecru Rowan pile wants to be:
The Cornish Knit Frock by Jane Gottelier from the book Indigo Knits. I had a flirtation with the Whitby Sweater from the same book, but decided that in ecru it would look like any old aran, as it would not have the lightening effect that makes the cables stand out when using a colored yarn. Besides, Whitby is in Yorkshire, not Cornwall.
An added attraction is that the Cornish sweater was made by one of the Knitting Goddesses, Kay Gardiner of Mason-Dixon fame, and was done with the same yarn substitution I am using, Rowan Denim for elann.com Den-M-Nit. Happily for me, Kay demonstrated that the shrinkage of the two yarns is the same.
Plus there is the connection to Cornwall. My DH is from there, and we have visited family there many times.
Fisher ganseys are also on my mind because I am happily anticipating my sojourn to Cordova, Alaska this summer for the Fisher Folk knitfest:
And when I'm in Cordova, one of the workshops I'll be attending is an indigo dyeing session. I'm going to take my now-foofed 6 Juniper Moon CSA cormo skeins and dunk them in the pot.
For a while, I was conflicted about whether I should just do them plain indigo, or go for spaced shades of blue, or tie them up to get white spaces in the blue. Wait. Three techniques into six skeins divides evenly--I could do 2 of each! Hope the teacher agrees...
