When did save the date cards become popular? I’d never heard of them until I started writing for this site. Are they essential? Does everyone send them now? I do quite like the idea – I’m all for more stationery – but it’s extra expense, isn’t it?
Anyway, these particular cards are plastic and the same size and shape as a credit card (so your guests can keep them in their wallets, I imagine). There are various templates and styles available, of course. Have a look at the site.
