Oh how I love me some Kraemer Yarns Tatamy Tweed. It's very reasonable, has great knubbly bits and since it's cotton + acrylic, you can throw it in the wash.
The pattern is the Rufus Textured Cardigan from Vintage Baby Knits with some mods. I knit a different collar and also went with garter stitch for the cuffs. The buttons are vintage glass.
