How to draw a bubble letter O
- Sketch a skeleton circle.
- Inflate it into a thick ring, checking the width stays even all the way around.
- Centre the counter: the hole should sit dead middle, about a third of the letter’s width.
- Erase the skeleton and add a big highlight on the upper left — the classic balloon shine.

Bubble letter O questions
How big should the hole in a bubble O be?
About one third of the total width. Bigger reads as a thin ring; smaller reads as a solid dot — a third is the sweet spot that still says balloon.
What should I color the bubble letter with?
Anything — markers, crayons, watercolor. The outline is drawn thick enough to survive enthusiastic coloring, and the letter is big enough to cut out for banners.
