I was at the Wooden Boat Festival in Port Townsend, Washington, several weeks ago and picked up a simply labeled soap from the Mimsy Soap Ranch booth at the craft show. The label was perfect, with all the required elements!
It’s not too difficult to correctly label a soap or cosmetic … it just takes some attention to detail.
If you need help, or want a side check on your labels, you can get a Label Review to get your labels on track.
