I didn't know this style of card had a name until I saw the current Butterfly Challenge!
I really wanted to use double sided card for this, but the design I wanted to use only came as single sided. If I'd glued two sheets back to back there would have been nasty bulges that formed around the creases, so instead I followed the instructions over at the Butterfly Challenge to create my card in the blue paper, adjusting the measurements to use a 12" piece of paper which makes a 4" square card. Then I cut the other paper to fit all the panels leaving a tiny white space each side of the crease lines so that the card would fold.
I stamped and die cut the sentiment then decorated the outside with die-cut butterflies, finishing each with tiny pearls.
I am sharing this with :
The Butterfly Challenge - Quarto fold and Quinacridone (how I wish I'd known that word in my Scrabble playing days! - ACRID on the table and QUINONE in my hand would have led to a massive score!)
Allsorts Challenge - More than one word sentiment
