These background papers are using a technique suggested in Craft Stamper utilizing flowers and shrubbery from your garden and cut flowers.
These particular ones were pressed from a bouquet my friend got me for my birthday. Please note that although white ones work they tend not to stand out and are a grey shadow outline, darker colours make a stronger impression.
To do this technique sandwich two pieces of card over the pulled petals play with your cuttlebug or other machine to get the right sandwich and pass through three times then rotate both of the pieces of card and do again for a more intense and fuller effect.
I shall post my cards made with these shortly.
Hope you like my backgrounds and give it a try.
