I learned a beautiful technique a few days ago and had to try this.  It is called the bleaching technique.  I used gray card stock measuring 4 by 5 1/4 from  Recollections from Michaels.   First I used my powder tool from ek tools and powdered the entire card.  I did not want any stray embossing powder on the card. I stamped the Fancy Butterfly from So Suzy Stamps in Versamark ink.  I then heat embossed the butterfly with Black Sparkle embossing powder from Ranger.  Now here comes the fun.  I bought one of those Clorox gel pens that you can find in any supermarket in the laundry aisle.  After shaking up the gel pen a little, I squirted a small amount in my palette.  In another little section placed a little bit of tap water.  I had to use a whole new water brush from Pentel for this technique so that I did not get any ink from my other water coloring fun.  First I used the clean water and wet the entire embossed area of the butterfly.  Then I added a touch of bleach to the tip of the brush and then dipped it again in water to dilute it a little.  I covered the entire area of the butterfly with the tip and added more bleach and water as needed.  Once I colored the entire area I dried it with my heat tool.  The sentiment is from a no name brand of stamps which I stamped in Memento Luxe and heat embossed in clear.  Added this to a white card stock measuring 4 1/8 by 5 3/8 and then added this to a regular size A2 card base in black.  Hope you will try this technique and enjoy it as much as I did.  I can tell you that you will need a stamp that has borders and some detail on the inside of the stamp.  This is why the Fancy Butterfly worked so well.  Please try this and let me know what you think.
