Hi- I'm pretty new to cake decorating, and I've only ever used Wilton fondant and Duff fondant because those are what are available to me. I like Duff's flavor and texture better than Wilton's, but the white color is not a bright white- it's more of an ivory. Are there other brands (that I could order online, maybe?) that make a bright white fondant?
You can try Satin Ice Fondant, its pure white.
