I was working on a couple of fake flame baskets. Built a couple of big ones with window fans in the past but I needed them smaller to use inside. Found some baskets in the right size for the 4 inch, supposedly, high velocity desk fans I got at the Walmart. Well the fans aren't as high velocity as I hoped and barely lift even the lightest weigh fabric. Any ideas how to save this project short of trying to find new fans with more lift?
