I forgot I had more paid work to show you! I did this one a few months ago, it's a logo for a baby swimming school. I had no idea how you teach a baby to swim when they can't even walk yet, so watching the lessons was really interesting. Apparently there's a few tricks to it, like if you start before the baby starts trying to sit up then they'll be much more comfortable on their back in the water, and will have an easier time learning to float later.
The swimming school is called 'Dinky Dippers' and it's run by Nadine Santus, if you're reading this from the Cambridge area and you have a child under 4 who could use some swimming lessons.
