I'm making this scarf for my dad (minus the lovely flower) and twice the length in a dark charcoal grey. How would it look if about 1/2 inch from ends I added two medium blue stripes (each end would have 2 stripes, 3 rows apart and the stripes would be 2-3 rows a piece) The colors look gorgeous together, I'm just not sure if this pattern would work with stripes on the ends: http://www.islandofmisfitpatterns.com/2006/10/04/dee-luxe/
I tend to feel like a 'fancier' rib pattern like that should stand alone. I'd leave the stripes out.
I made that scarf for my dad, too. I used a tweed yarn....I liked the fancy rib.
You'd get two-color purl bumps--to me that always looks like something is wrong.
I say nay I think it would look much better without it. The scarf is nice as is!
