Boom is such a powerful onomatopoeic word and we think this poster captures the BOOM sound perfectly1
Whoosh is one of my favourite onomatopoeic words. You can almost feel the firework whooshing through the sky, or the email whooshing out of your inbox! One minute it is there, and next - whoosh - it is gone!
The letters on our POP poster really seem to pop out of the page, and that was our intention! Pop is such a fun word to say, and to spell, and of course it is also onomatopoeic.
