I don't have much on the walls in the way of artwork at the moment, there are a few hearts floating about however but that's it, so when we moved in to our new flat I thought it would be a lovely idea to save some of the cards we were given and use them this way. So I got a nice cheap frame I had and stuck the card in the centre and voila.
To be honest you could use a much nicer frame, this was just one I had lying around, but its a great way of keeping those special cards instead of just having them all tucked away in a drawer somewhere.
You could do a whole wall of them from special occasions ! Maybe I'll go search my drawers !
