I'm kinda leaning towards the grey-greenish-darker yellow-ish gold-ish (is there a really a word to describe this color??) thread, I think. I like the gold-tone in it, and is just slightly contrasting to the top. I'm thinking when quilted the pattern will look more like a shadow like Karen's picture (if I'm remembering her name right) and kind of stick to the traditional feel of the wholecloth yet will have enough contrast to show the stitching. I'm also contemplating maybe using the other green for the borders to frame it, but I'm not sure. That way I can use the topper by itself, too, and not just with the runner. Thank you everybody SEW very much for your input. I'll definitely post a pic when it's finished. :)
