Here is how I started , using Melanie Muenchinger's set "A Year of Flowers" by Gina K. Designs, stamped the flower using London Fog Memento ink.
I then sponged the center and on upper part of the petals with New Sprout by Memento
Then I used Copic's R01 coloring the bottom part of the petal and blending into the green. Next I used R20 to darken and blend, as shown. The leaves were colored with YG13 then I added G24 and then
a little YG67 for shaded areas. For the center of the flower, I used Orange and Yellow Stickles. After coloring the flowers and the leaves, I cut them out. I sponged the back panels with Cantaloupe by Memento and then Rose Bud over that. These colors make a gorgeous peach color that goes well with GKD card stock "Just Peachy. You can see how this was done on Theresa Momber's tutorial here.
After seeing where I wanted the leaves placed I glued them down and cut out a few flower petals (just for a different look), then attached the flowers using pop-dots. Well that is all and I hope it was helpful.
