I was lucky enough to receive more Cadena l from Illimani Yarn, the Canadian yarn company based in Montreal. This alpaca/merino blend is such a pleasure to work with and the drape is amazing, just what you need for these oversized pieces.
The Day Coat uses approximately 539yds/492m (11 skeins) of Cadena l and US #19 (16mm) I would rate this as an easy pattern, good for an advanced beginner on up. It's a one size pattern but using the schematic and the notations included is easy to adjust if needed.
