Tips

  • Don't worry about being too careful when painting; the black outline will tidy up any imperfections.
  • If paint pens don't flow smoothly, pump them on paper to increase paint flow.
  • Apply sealer outdoors in a well-ventilated area with a drop cloth underneath. Use light coats to avoid running.

Common Mistakes to Avoid

1. Uneven Paint Application

Reason: Rocks are unevenly covered with paint, leaving patches of bare rock showing or creating thick, gloopy areas.
Solution: Use thin coats of paint and allow each coat to dry completely before applying the next.

2. Letters Too Small or Crowded

Reason: The birthday message is difficult to read due to tiny lettering or letters being too close together.
Solution: Use stencils or freehand larger letters with ample spacing between each one.

3. Rocks Too Heavy for String

Reason: The string breaks or the bunting sags because the rocks are too heavy.
Solution: Use a stronger string, such as twine or baker's twine, and space the rocks further apart on the string.

FAQs

What kind of paint should I use for the rocks?
Acrylic paints are best for rocks because they are durable and waterproof, ensuring your bunting lasts longer. Choose vibrant colors for a festive look!
How do I make the rocks stay on the string?
Drill small holes near the top of each painted rock and thread a sturdy string or twine through them. You can also use strong glue, like E6000, to attach the rocks, but be sure to let it dry completely before using them.
What if my rocks aren't perfectly smooth and round?
Don't worry! The imperfections of naturally shaped rocks add to the charm. Just paint them in fun, bright colors, and the uniqueness of each rock will make your bunting even more special.
