Useful notes : white is a deadening colour. Often cream or off-white works better than brilliant white which can be too harsh. The gold metallic worked better than silver, which just disappeared into the background. The crown pattern works well viewed close-up, but doesn't translate quite so well from a distance. I might have another go at the design, and tweak it a bit.
(The Fair Isle book, by the way, is '200 Fair Isle Designs' by Mary Jane Mucklestone. Published by Search press. A lovely publication.)
And finally ... don't these luscious colours make you want to pick up a needle?
