I am a Flower Essence practitioner and I sell sprays and essences. Each spray contains flower essences and premium essential oils. I use the gloss labels and Epson's claria ink to make them a bit more water proof since the products contain water. I find the Online Labels to be perfect for the job!
In order to get the background color, a simple step is used. I create a text box over the entire sheet of labels, color it and take down the transparency to 72%.
