Sport weight swatches

I have a one pound cone of Bartlett Yarns sport weight still in my stash. I think it is the beginning of many light weight heathered wool cardigans with something going on along the edges - something like beads or crochet. I keep looking at the cardigans in Rowan's A Season's Tale and looking at crochet edgings. I've been thinking of a sweater the color of old bricks with a faded advertisement knitted in - something like this.
