7 bubble letter fonts made for stickers, party signs and kids' crafts

Bubble letters are the friendliest corner of the whole graffiti genre, and the most useful one if you make things for children or sell party printables. There is a catch, though: a lot of rounded alphabets look wonderful in the designer's preview and turn into an unreadable blob the moment you shrink them to sticker size. The enclosed spaces inside letters like A, O and R close up, and what was a cheerful word becomes a smudge.

These seven all passed the same test. I set the word hello at twenty millimetres wide, printed it, and looked at whether the letters still read. Every one of them keeps enough space inside the curves to hold a second colour, which is what you want when the outline is one shade and the fill is another.
