I found the stamps I used for these cards on E-bay, they were very good value.
I think sometimes the simpler the card the more elegant it looks.
I was given the tortoise buttons so then just stamped the sentiment with ink the same colour and embossed with clear embossing powder, threaded bakers twine through the button then attached the button to the card with Pinflair glue gel.
Hope these sell as well as the other cards!!!
