I adore beer & wine bottle labels. So much so that I'm not only collecting them, I'm dressing up like them ^^ (And, if you're anything like me, you too make your beverage purchases based on the packaging design. Y'know, it's logical.)
Before any glass bottles are tossed into the recycle bin, save the sticker!
Easy: fill up the sink or a pot with hot water and soak the bottle for a bit (fill the bottle so it sinks), and the label will safely peel off in one piece! Beware that the glue may still be a bit tacky.
