MY TUTORIAL FOR BEARDED IRIS
Sizzix has a tutorial posted with the steps Susan Tierney-Cockburn did showing how to assemble the bearded iris at this LINK. Below I have a tutorial showing how I created the yellow and rust flower.
Susan's Garden Rust Pan Pastel around the edges of the petals, on both the front and back.
Susan's Garden Flower Tool Kit, to add character lines to the petal.
Susan's Garden plastic flower pot tray to help hold their shape.
