Goldify is a nifty pre-made Photoshop PSD that allows you to turn plain text or solid shapes into golden works of art. Just download it, unzip it, and start creating.
If you're new to Photoshop, no problem! I've provided instructions inside the file. You should be able to get started right away.
If you have a fair amount of Photoshop experience, and know your way around any ol' PSD, feel free to go in and make your own modifications to the effect layers.
For best results, once you're happy with your golden work of art, convert it to a smart object and resize it to your liking, or insert it into a new photoshop file and tinker away!
