I bought some new paper to try out. It's called Clairfontaine Fontaine 300g HP. Just did this doodle to see what it was like. I used mixed watercolour pencils.
Didn't particularly like it as I found it a bit too grainy with the pencils so the next day I had a go using watercolour paints on it.
Got a much nicer result with it so will be sticking to using the watercolour paints on it, I think.
