I've used the flower head or dandelion or fireworks stamp from the Penny Black stampset Trims.
Multiple stamping to fill the whole background.
Then I sponged on some distress inks in bright colors as if they were flowers and blue for the background/sky.
Covered it in vellum, with the Simon Says Stamp from Birthday Balloons.
White heat embossed it on the vellum.
Wrapped the vellum around the card and glued it to the panel on three sides.
Added loads of sequins and confetti in similar colors to the panel to make a frameless shaker card. then glued the fourth side shut.
