Everyday Cricut, before that I just over thought the whole process.
Paper: Stamper's Select White (card face most of the "S", one layer of the brace and both layers of the zap base) and Hibiscus Burst (card base one layer of the "S") and from Papertrey Ink, and some light pink, maroon and blue scraps from my scrapbox.
Cricut cartridge: Superman (including the font).
Foil: Martha Stewart from the foil kit.
Embellishments: Crystal and Cotton Candy Stickles, Pearl Ex Powder.
After I was sure that was what I wanted I glued the blue shadow to the white cardstock and outlined it and all the openings in it with Crystal Stickles.The white part of the icon is covered with white Pearl Ex powder. The Hibiscus Burst background is coated with Crystal Stickles and edged with Martha Stewart Foil. I made two more icon bases to make sure it wouldn't warp. Then the whole icon was covered with Triple Thick Gloss Glaze by DecoArt and attached with foam tape.
