I don't usually use black cardstock for a card base. The challenge at Make the Cards Challenge is use black background. So black card it is.
The vellum layer is from SU called Lovely Layers andis pre-printed with the black dots creating a perfect frame for the patterned paper which is from SU's retired Hand Penned DSP. It is originally b/w and I colored the flowers with Calypso Coral SU blends, then framed that with black cardstock and adhered it to a Calyso Coral card. That is all adhered to the black card base. The sentiment is an old SU one, stamped and fussy cut.
