The only thing I don't like about watercolour, is the drying time. I use a lot of water when I use watercolours, so it takes forever to dry. Yes, I could use a hair dryer, but then it dries too fast and you don't get the right look, at least I think that. Its the same reason I don't use oil paints. Besides not being able to use them because they set off allergies, (wear a mask, have a window near by when painting when younger people :p), they take too long to dry for me. Not sure if I mentioned here, but the asthma nurse has said I have Occupational asthma , so can't actually use materials I use to use without wearing a mask or outside. (If it ever stops raining here :p). Told me its actually pretty common in artists, they just ignore it tho :p So don't ignore it lol Pretty much stuck with acrylics, pencils, watercolours and etching plates. But need a window open or a mask when using the inks for the plates.
