Novelty pillowcases These novel pillowcases feature a heart design, but with a slight twist. Rather than getting a heart on each item, the Union pillowcases are cleverly designed to provide half a heart on each piece. When the pillowcases are put into use on your bed, and the designs placed next to each other, they join together to form a heart – ahhhh. Slightly cheesy, but a cute idea, a pair of hand printed Union Egyptian cotton pillowcases costs £25 from Twisted Twee.
