Directions for Unicorn Birthday Party Balloons:

Step 1: Inflate balloons using helium tank then tie with gold ribbon.

Step 2: Add flair to balloon tails by tying trim to balloon knots.

Add some rainbow ribbon and some texture or shapes, using garland.

Step 3: Add additional texture to balloons with stickers by making a pattern all over balloons with star or circle stickers, concentrating stickers toward bottom with a few floating toward the top for a “dipped” look or mixing different stickers together.

Step 4: To add some splatter paint to balloons as “unicorn tears,” start by squeezing different paint colors onto plate.

Step 5: Hold balloon over covered surface and dip stiff paint brush into one color. Flick brush at balloon to create splatters.

If paint is not splattering well, dip brush in small amount of water first to help thin out paint.

Step 6: Rotate balloon and repeat previous step to evenly distribute color.

Then move on to additional colors until balloon looks as desired.

Let dry a few minutes. Repeat with remaining balloons.

Note: Popcorn ceilings and hot ceiling lights can pop balloons. If high ceilings are a concern, tie balloons to jar of rainbow-colored rocks or candy in the party’s color scheme.
