One Stop Craft Challenges is to use a fireworks theme or colours.
I have used an embossing folder on my handmade backing paper, which I coloured with Dylusions and and Moon Glow's Glitz Spritz. I added some extra sparkle with a Twinklette pen, but it doesn't show up too well in the scan. The orange flower is a peeloff from Starform Stickers, and the best wishes peeloff has been in my craft stash for a long time (I coloured it with a black marker.
The embossed folder looks like an exploding firework to me!.
