One of my all time favorite techniques from the Technique Junkie newsletter is Antique Glimmers from the December 2009 issue. All of the stamps on this card are from the line of stamps offered by Technique Junkie Stamps, formerly known as Stamp Camp. http://www.stampcamp.com/ I used a Copic marker to color the moon peeking through the clouds at night. The background tamp was used without an acrylic block, but curved in my hand -- stamping different areas of the stamp at different angles to create that look.
Have a wonderfully creative day!
