I had a touch of the Tweed Madness about a month ago, which resulted in my purchasing some pink and red tweed yarn:
Some Rowan Felted Tweed and Rowan Scottish Tweed 4ply.
I'm using the Felted Tweed for a cardigan, it's Ginny by Kim Hargreaves.
This is the back. I have one front finished as well, and now I have stalled out on the second front part. . .My tweed madness needs to return if I want to get this all done in time to wear this season!
