Hi Everyone! I've been struggling for awhile now figuring out how all the wax melt vendors have a million and one scents, I'm guessing scent blending?? Can anyone tell me how to scent blend? Also would love your recommendations on scent vendors. And color, how do these wax melt vendors have such pretty colors?? Do they use liquid dye or chips? Wax color vendor recommendations are more than welcome as well!
