My favourite coffee (at the moment, at least) is the Ethiopian Yirgacheffe from Bridgehead Coffee here in Ottawa. It's a medium roast with a lovely floral, citrus-y flavour and is best when brewed strong. Unfortunately it's only a limited edition, and I don't know what I'm going to do when they don't offer it anymore. Bridgehead only stocks fair trade, shade grown, and organic coffees (their tea and chocolate meet these requirements too), and all of them are delicious.
As for yarn, I love working with anything from Mista Alpaca. I've been playing around with some swatches using their laceweight, and nothing drapes like baby alpaca for shawls and stoles.
