I had a little last minute Halloween decorating inspiration, and I designed a paper and ribbon Trick or Treat banner. I took my time creating this, but if you're moving right along, this should take you two hours or less.
Print out letters -- I used this template from marthastewart.com
Black paper -- construction paper or thicker
Scissors
Glue stick or rubber cement
Colored ribbon -- I bought this black and orange striped version from Hobby Lobby
Orange marker
Hole punch (a 3-hole works fine)
Bowl
Pencil
Glue gun (optional)
Step 1: Save the letter template to your computer. Using Photoshop or Microsoft Office Picture Manager, crop the letters you will need and save them as individual files. This way you can print the exact letters you need, and be able to size them to your liking.
Step 6: Embellish your letters. I simply added some orange around the star in each letter, but you could draw curlicues, color the letters completely, draw pumpkins, etc.
Step 7: Cut enough ribbon to string your letters, plus an extra foot to give you some room to work with. For this banner, there are 12 letters 5" across, so multiply that and you'll need roughly 6' of ribbon.
Step 10: Find a place to display your banner and enjoy!
