Cornish Cream. Off-white linen saltwater linen cushion cover – Cream Cornwall. What a beautiful combination of ethereal starfish, a rare sand dollar, [have you ever been lucky enough to find one washed up on the beach?] and a whelk with a gorgeous turquoise interior, against a piece of inky blue seaweed . Choose from two basic colours; off-white or natural linen for this beautiful cushion.
