New project: it isn't a sweater, it's a jacket

I've been inspired by customers - ever since I started to carry B&L yarns, my most enthusiastic supporters have been from Japan. The most popular varieties are Super and Country Roving, and I wish I could read japanese so that I could follow their blogs and find out what they are making. But it's a pretty safe bet that they making cowichan style sweaters.Oona loves everything japanese, so jumped at the chance when I asked her  if she'd like a cowichan style jacket. Funny story: in one of my favorite plays, there is quite an argument between the two characters as to whether a garment is a sweater or a jacket. When I designed the costumes for it so many years ago, those lines brought to mind my father's old zipped cardigan - my grandmother had knit it using a Mary Maxim pattern and lined it throughout.Years later, Marcel was cast in the role of Ernest and the costume designer found a pictorial Mary Maxim for him on Ebay. Maybe it's because I'm now a knitter (I wasn't for the first go-round of Ernest and Ernestine), but I found the costume choice hilarious.Back to Oona's SweaterJacket - real Cowichan sweaters are  knit using thick single-ply handspun yarn (it should also be noted that only authentic garments made by the Cowichan band on Canada's west coast have a right to be designated as 'Cowichan Sweaters'. As such, no hand knitting yarn has been commercially produced which can be said to be authentic). Over the years, several companies have offered yarn specifically for this type of knitting - White Buffalo and Briggs & Little among them. Since White Buffalo yarn has been discontinued, many now opt for country roving but, sadly, it isn't available in a clear, bright yellow - and Oona is all about yellow. So, I'll be using Super. The yarns I chose can be seen above and here is my sketch. Next, I'll need to swatch and draft my pattern pieces.
