I would love to make a cardigan in worsted weight in your beautiful red color.
My favourite colour mix are two (any two) really rich colours that blend over a longer colour change, I love Rich Red and Rich Blue colour changing, making a fabulous purple.
My favorite yarn is Brigantia and I would love it in red. I would make a cardigan.
I love fingering wt blue-faced leister yarn and also corriedale. I find they are workhorse yarns. When using for socks I try to find them blended with mohair or nylon.
With fall - hopefully - coming, I'd go for Brigantia in Ring of Brodgar.
Periwinkle in Brigantia. I'd make a sweater.
so tough to choose, but I've been coveting Herb Garden on Brigantia since I saw it in your blog post back in April.
