I CASEd this fold out card from Libby Stamps.  It features the Art Gallery Bundle (156227) in the January -June Catalog.  Also features the Fine Art Floral DSP (154558), Golden Garden DS Acetate (154557) and Label Me Fancy Punch (151297),

I used a 4-14″ x 7-1/2″ piece of cardstock scored at 1″ and 6-1/2″ for the card base. I layered the DSP with the Acetate and cut a 4″ x 5-1/4″ piece, then adhered the DSP to the right flap and then the acetate on the left flap.
