By pressing a label with a cloth soaked in hot water, the glue on the back becomes "un-sticky," and you can easily peel it off!
Soak a cloth with really hot water and press on the label, rubbing gently.
Begin to peel the label as far back as you can.
If it is still stuck, press more water onto the label and underneath it.
Continue peeling until it is all gone.
Ta-Da! A beautiful label-less bottle just ready for crafting!
