Removing the wine label is a great idea. Rather than saving an empty bottle of wine, you can remove the label quite easily and mount it into a journal or scrapbook.
Fill the bottle with hot water, and then soak it in warm, soapy water. After an hour, the label should be floating off the bottle or clinging loosely. If it is still stuck, continue soaking for an hour more, even overnight if necessary. For a stubborn label, carefully use a single-edge razor to scrape the label off. Once the label has soaked off, place it on a paper towel, adhesive side up, blot, and allow to dry. Now you have a label ready to be placed in a scrapbook or journal.
