Creating custom glitter-patterned stickers involves printing designs on shiny paper, specifically reflective or metallic paper. While commercially available options exist, the discussion revolves around DIY methods for making such paper. Techniques suggested include using spray adhesive to apply glitter, creating silk screens for adhesive printing, or exploring vacuum deposition methods, though the latter may be impractical for home use. Reflective inks and glitter materials are distinct; glitter requires small reflective surfaces that cannot be effectively printed using standard inkjet or laser printers. Alternatives like using patterned iridescent papers or metallic inks are recommended. The goal is to achieve a design that appears to glitter and changes brightness with light angles, which may be best accomplished by printing on reflective surfaces with strategic spacing. Crafting methods like laminating foils or using patterned foils through laser engraving are also mentioned, though they may be complex for DIY projects.
