This card is an old favourite. I have made something similar a number of times as a box card but this was my starting point for a 'Mrs and Mrs card. This stamp is no longer available but it is so useful. It took a lot of practise to get this lined up and stamped correctly as the stamp actually says - Mr.&Mrs. So yes this was very fiddly putting an s in where there wasn't one.
The centre heart is also a retired stamp, in a pale colour it makes a great background or in a vivid colour it can be the focus. The little flowers one swirls of pearls just add to the femininity.
