I also designed a simple little cake banner.
I took two barbecue sticks and wrapped a thin strand of baby pink ribbon around them. I used non-toxic, child friendly glue to attach the ribbons and made sure to leave space at the bottom for the sticks to be inserted into the cake.
I glued the excess ribbon to the tops of the sticks for streamers.
I designed a simple banner on MS Word (I need to teach myself how to use Illustrator) to compliment the candle I picked out.
I printed the banners on bond paper and stuck them to board paper to so they wouldn't be flimsy and tear easily.
Note: On hindsight I should have printed it directly on colored board paper to save on paper, ink and glue.
I cut out the banners and attached them to the sticks with clear tape, which blended in very well. Another idea I had was to attach the banners using matching decorative stickers but I didn't have any. Washi tape is another idea.
I'd also like to try making cake banners like these below.
