I love watercolour but it's one of those things that I'm not that brilliant at, in fact painting in general is definitely not my forte, so when I discovered you can do watercolour like effects in Photoshop I jumped on it! I'm on a typography kick at the moment so I've created a tutorial that shows you how to make watercolour text in Photoshop. I know there's tons more techniques out there for this sort of thing but I think this is a great starting point, also if you've got my favourite typography book Handmade Type you could do a digital vs handmade lesson with your students and have a go at creating watercolour text by hand in the style of Natsuki Otani.
Enjoy! - Claire ❤
