I love this blue dye! I don't think the smell is that bad at all, unless you hold it up to your nose and smell it right out of the jar, and you can't smell it AT ALL in the finished product. This is a wonderfully vibrant blue, when used in soy wax, and I like how easily I can blend it with other colors. It combines nicely with brown dye for a richer, navy blue, and I can darken it up easily with a few drops of black. No complaints here!
