Whether you’re declaring undying love or dropping a deliciously intriuging hint, the right Valentine’s card does a lot of heavy lifting. This year’s selection runs the gamut from witty and whimsical to beautifully, unapologetically romantic – with a few literary and design-led gems thrown in for good measure (and, of course, good taste signalling – no small thing, lest we forget, when it comes to seduction). Some are charming, some are funny, some are almost too pretty to give away. But give them away you must if romance is to be on the cards. Just remember to seal yours with a kiss.
