Things You'll Need
Hot glue gun
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 save costs over purchasing an umbrella hat from a specialty store.
Find a small umbrella, one meant for a child to use, as a larger umbrella will be difficult to support on the hat.
Cut most of the handle off the umbrella using a miter saw. Leave only about 6 inches of the handle.
Smooth down the cut end of the umbrella handle with a fine-grit sandpaper.
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.
Cut out the traced circle so you have a hole at the center of the hat.
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.
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.
