Set up a workspace in a dry, out of the way location with a flat surface.
Tear off a sheet of wax paper and lay your palm frond flat on it. Place another sheet of wax paper on top.
Place heavy books on top of your palm frond, evenly distributing them so that no one part of the frond has more weight on it than another part.
Place silica gel packets around the pressed frond. Let the frond sit for two weeks. Check on it occasionally to see how the drying process is coming along.
Remove the books and peel back the wax paper. Take the frond to a well-ventilated area and place newspaper beneath it.
Don a face mask and spray the frond with acrylic spray. Flip it over after half an hour and spray the other side. Wait another half hour.
Spray the frond with a matte finish to remove the glossy appearance of the acrylic. Wait half an hour before flipping the frond over and spraying the other side.
