These flowers work perfectly for shadow boxes because they are very three-dimensional. I love, love, love the look of these flowers! For the flower shown above, I inked the edges of the petals with glimmer mist in Tattered Leather (brown) to give it more of a vintage feel. To attach the pins, I pushed them into a small piece of chipboard which I hid behind the flower. By pushing the pins into chipboard, you avoid getting painful pin pricks.
I hope you enjoy making these flowers! I certainly did! :)
