My beautiful banner, it came out so well and it was just so easy to do it cracks me up :).
So, here's how I did it.
Scrapbook paper: scraps of different but coordinating colors.
Glue or double sided tape
Letters (I used my Cricut with George cartridge)
Posts (I used straws)
First, make your triangles. You should have however many pieces you need. They should be at least 6 inches tall and 4 inches wide or so. Fold in half. From the bottom (open end) cut a V ensuring to leave the top closed. Use glue our double-sided tape on the inside to keep it flat.
Second, make your letters. You can make them by hand for a more tousled look. Or if you have punches or a Cricut machine, you can use those too.
Third, using a beading technique, slide the string into your letters. Make sure you are putting them in order so you don't misspell your word :).
Lastly, hang up on post. I simply tied my string to two straws and poked those into the cake :).
