DIY Giant Sign

Here is a simple and quick method I discovered for making a giant banner sign:
1) Draw letters on construction paper.
2) Cut out letters, doubling up for letters that are used multiple times.
3) Lay letters out on banner, adjusting letting and kerning as needed. Using spray adhesive, stick the letters to the banner.
4) Tape over the letters with clear packing tape to make the banner water proof.
