I have tried watercolour painting in the past, although I must admit I much prefer to look at watercolour paintings rather than attempt it myself.
My father used to do a lot of watercolour painting - his specialty was floral scenes and they were beautiful. He even managed to sell a few of them at a local art museum, which was a huge success for him at the time.
Like Citizen68, I also enjoy watching TV programmes related to painting, although I haven't seen that particular one. Do let me know if you remember the name!
