An umbrella hat is a traditional baseball cap with an umbrella topper attached to it. Hats like this can be worn when out in the sun to keep you shaded, or just as a gag with friends. If you're looking for an umbrella hat of your own, consider making one yourself. You'll just need a few basic materials and tools, and making this item yourself can...
M/F Find a small umbrella, one meant for a child to use, as a larger umbrella will be difficult to support on the hat.
M/F Cut most of the handle off the umbrella using a miter saw. Leave only about 6 inches of the handle.
M/F Smooth down the cut end of the umbrella handle with a fine-grit sandpaper.
M/F Place the end of the umbrella handle at the top center of the baseball hat. Trace the outline of the handle onto the hat with a pen.
M/F Cut out the traced circle so you have a hole at the center of the hat.
M/F Push the handle of the umbrella through the hole in the hat, so that just 1/4 inch of the handle is on the underside of the hat. Place a line of hot glue along the edge of the hole and hold the umbrella in place until the glue dries.
M/F Reinforce the umbrella in place by placing strips of masking tape around the handle at the top and bottom. Place a square of tape under the end of the handle so that your scalp won't get scratched when you're wearing the hat.
