The pattern is Madrid by Alexandra Brinck and is available as a free Ravelry download . It calls for 4 ply yarn - I used Rowan Cashsoft 4 ply which is lovely and smooth and soft. It takes only about 25 grams for the pair of wristlets. They are reasonably easy to make but you do have to concentrate on the pattern - I had to correct a number of errors I made due to day dreaming!
I'll definitely be using this pattern again - Eve wants a pair!
