What do we think of them? Personally, I think they're ostentatious tasteless too big a waste of money!
I don't go out and buy 'individual' cards for family/close friends - most of them are pretty tacky and they cost so much! Family either get homemade or nicer-than-normal cards from a charity pack of 10, but I've never felt the need to buy family members 'special' cards. Does this make me a humbug?
My PIL and SIL always get us a 'special' card and while I think it's a nice thought from them, the things are horrible in themselves! So there are two of them hanging off the bannisters and I'm not kidding, they're the size of a sheet of A4 paper!
