1. Cut the felt into two 6-inch x 12-inch strips.
2. Fold each strip of felt in half lengthwise.
3. Glue the two strips of felt together along the folded edges.
4. Cut a small hole in the center of the felt strip.
5. Thread the string through the hole in the felt strip.
6. Tie a knot in the string to secure the felt strip in place.
7. Mark the dowel at 6 inches, 9 inches, and 12 inches.
8. Place the felt strip around the dowel, aligning the holes with the marks you made.
9. Glue the felt strip to the dowel.
10. Allow the glue to dry completely before using the balloon sizer.
To use a balloon sizer, simply inflate a balloon until it reaches the desired size. Then, place the balloon over the sizer and release the air. The balloon will deflate and the sizer will hold it at the desired size.
Balloon sizers are a great tool for creating custom balloon decorations for parties, weddings, and other special events. They are also great for teaching children about different sizes and shapes.
