Fleur di Lis Tanning stickers are a great way to measure your tan. It is always hard to see your own tanning progress by looking in the mirror. Tanning is a gradual process and therefore your color changes throughout the day and from one day to the next. The best way to measure your tanning progress is to use a Fleur di Lis tanning sticker in the same spot each time you tan. Almost everyone is surprised by how tan they actually are once they have used a Fleur di Lis sticker for a few weeks.
