I’ve been a big fan of the “marbled” look since I worked at a paper store years ago. We sold gorgeous sheets of painted marbled paper. I used one to cover the inside of a glass lamp and years later lined my daughter’s dresser drawers with similar sheets.
Real marble is just gorgeous, of course, but the faux stuff can be beautiful and eye-catching too. I’ve rounded up a few examples (and even a few links to simple DIYs to get the look yourself!).
