Look out Primas! Amanda from Cricut Creations has the skivvy on dying flowers with various inks and chalks (http://amkscrap.blogspot.com/2008/10/dying-flowers-with-inks-tutorial.html). She has gone into super detail and pics to tell us all her tale of travels through the dying process and the results along the way. Her tutorial is done with purchased "stem" flowers, however... I'm sure this could be applied to paper flowers that have been shaped and formed, as well.
On another note... she is offering a "RAK" (blog candy!). I don't know what the difference is, but she is giving a gift to one commentor chosen at random. This could be you! Go visit her blog (see the link above), learn a new technique, and post a comment. You have nothing to lose. Plus! If you continue to visit her blog (or subscribe...) you can learn many other things... she's always got something great! Toodles for now! lisa
