I found this really sweet image on one of my Crafter's Companions Humphrey's Corner CD-Roms. I can't remember which one the images came from (either Crafting Collection or A Year with Humphrey) as I was dotting between the two. The spotty yellow paper which you may just be able to make out, and the purple text paper is from the CDs too. The yellow paper was digitally recoloured within the program to make it paler and less orangey.
Jennifer McGuire's blog, but I'm afraid I can't find the direct link to her post. It is very easy to do. Just put little dabs of strong glue on your flower image, then working above your project, scrape your scissors along the edge of some coloured card. Little fine fluffy bits of card will fall on to your project and stick to the glue, giving a wee bit of texture to your flower.
