Okay, so the LCD style message show on the card above isn't too appropriate to this time of year but as it is a 'write your own message' greeting card you can make it say whatever you want it to say. It is bought as a blank card with an embossed LCD grid for you to write over and produce your own eighties looking message. A copy of the alphabet is even supplied with the card so you know exactly what line should go where.
The card is created by the Yellow Owl workshop who sell the cards individually for $4.50 or as a set of five for $18. As they are an American company you may think twice about whether the shipping fees make it worthwhile ($9.50 for a single card) but it remains a great idea. Available to buy in shops in US is wrapping paper printed with the same grid which you can see beneath the card in the image.
