I used a couple strips of Washi Tape behind the bow and flowers. I found the buttons in a dollar bin at Michaels - they had a bunch of bright colors.
I described how I colored the Petaloo flowers in a previous blog post - except I put rhinestones in the centers instead of pearls to match the rhinestones in the banner. For the leaves, I used a Sizzix Sizzlits die from the Flowers, Branches, & Leaves set. To color the leaves, I used Tim Holtz Distress Crackle Paint in Peeled Paint. I added water to the Peeled Paint to thin it before painting it on, leaving some of the green card stock to show through. Then I painted on Rock Candy Distress Crackle to give them more crackle and some shine. Finally, I painted on Distress Reinker in spots to give the leaves some shading (I can't remember if I used Crushed Olive or Forest Moss) - it also helped to define the cracks in the paint.
The A7 sized card and envelope were cut using Sizzix Pro Dies.
