I have been looking at buying some capes. When I looked at the pattern for the blue-wing olive, it said that I needed to use blue-dun hackle. But when I looked for a blue-dun cape I could only find dun. Are they the same?
Blue dun is a particular shade of Dun. I think you will be well served to look for a “medium dun”. It will fit and cover many more patterns as well. The shades of the same names between companies can vary as well.
That was a term that was used years ago. If you want to see a beautiful dun try to get a look at a dun cree from Collins, they are a work of art from mother nature with a little help from selective breeding.
