What properties should a typeface or font for children's signage have while still being playful?
I am looking for a typeface for use with children's signage (don't say Comic sans). I'm looking for something playful yet legible. By children, I mean elementary school age (and younger).
What a re properties in typefaces I should look for to find such a typface? Actual typeface suggestions are welcome, too.
I'm fond of Lemonade. Surprisingly readable for all that it's "cutesy."
