This is a pretty cute idea. I've also seen people do something like it with elmers glue this seems like it might be a better alternative. Use your hotglue gun write words on your pretty bottles then paint them pretty solid colors. Could make cute vases, decorations etc.
Hot glue + a mason jar + spray paint = great DIY project. I have so many ideas of ways to decorate these!!
Hot glue gun, Some mason jars & Spray paint (can use words or designs); great idea!
another cute craft idea for mason jars or wine bottles or such - just hot glue and spray paint
