For one of the toys in Lily's first birthday party favors, I made custom-printed bubbles. They were super easy, and super cheap!
I bought a discounted 24-pack of bubbles for only $3.59. I was lucky that 2 of the 3 colors were the same colors I was using for Lily's baby-friends party. (pink and yellow)
I peeled off all of the labels.
I then made my own label using Microsoft Publisher. I created a custom page size that was 4.5" x 1" and added my own colors, text, and polka dots.
I printed and cut out the labels I had created, and used a glue stick to glue them onto the bubbles.
Start to finish took about 30 minutes. The final product ended up costing me just 15 cents per bottle! You can't beat that.
