To see an example check out my "Cards" in my gallery.

What I do instead of buying the pre-package flower embellishments that can cost quite a bit I buy flowers at Michaels or JoAnns, especially the ones that are sold in a bunch. Then I pop the flower off the stem and take them apart so that you get like 4-5 layers of petals. I keep them in a ziplock, so they don't get wrinkled and then when I want to add them to a page or a card I can stack them or mix the colors, I put a brad in the middle to connect them and then there is enough space in the middle to allow you to add whatever you want.

Hope this helps.
