I've just been refurbishing a couple of nice solid stools. The one on the left has been done with a mixture of 2-tone seagrass and blue Danish cord, and the one on the right has 2-tone seagrass along with standard seagrass.
The blue Danish cord is unique, I believe. I got a roll of it from the factory shortly before they closed down for good, and was reliably informed that this was an experimental colour which never went into production. It's a really nice shade of blue, and the stool reminds me of a clear sunny day in winter, with the bare branches of the trees against a blue sky.
I was very tempted to keep them for myself, but they are for sale! Just £76 each, plus postage. Haven't got around to listing them on the site yet, but fire off an email if you're interested.
