Red and black are the only colors of satin ice I have used but I honestly cant remember if I have used to them to cover a cake yet. I mostly use them for detail work and things of that nature. I have never tried fondx. I’m a little worried because I don’t have a ton of time to figure this out! The wedding is August 11th and My client still hasn’t sent me her deposit. Maybe I can get over to a local supply shop and give a small tub of fondx a try to play with. Something that is forgiving and doesn’t dry out too quick would be preferable as I am used to working with wilton fondant..and in the dry so cal heat in the middle of August I know I will need to work lighting fast if I use satin ice.
