Valita's got some simple straight-forward instructions for making the flowers here - to use a punch and cardstock, slit between the petals, then turn them over and using an embossing tool, round the petals from the reverse side. Then you flip it over and indent the center. It's a "make your own Prima flowers" thing, and seemed to work best on the small flower. I'll keep trying and eventually persevere!
