This is a thread I'm thinking about for quite some time but never took time to make it as I have a very specific idea of what it should be and see so many ways for it to go wild. So I'll try to explain it as clearly as I can and provide some kind of format for everyone to follow to provide inputs. The origin: being far from an experienced painter myself, I frequently bump in the same trap which is forgetting what I've learned previously. This makes my progress curve going up and down. I realised that each time I don't stick to a couple of painting basics, I get lesser results or even worse, I screw something that started nicely. The idea: create a thread where everyone will share fundamental rules she/he follows otherwise the painting level will lower. What the thread is: a list of the most core rules to follow to, at least, keep at consistent painting level thus improve it in the long term. So sharing the same rule several time is more than wanted as it will help to identify it as a must. What the thread is not: this is not a list of tips and trick or advice for a specific technic and definitely not a "who's got the best advice of all challenge". Please don't think of what as not been shared already so you'll put something original, focus on what is YOUR absolute must-follow rule, even if already listed. To keep it synthetic, please use the following format: Mantra: a short sentence/title that tell the substance of the rule A small paragraph to explain a bit deeper the what and the why (not mandatory) Two or three mantras maximum allowed per participant. We want to focus on what is essential. In the end, we may have something like 10 recurring entries (which is already a lot). I'll tried to gather all the entries at the top of the thread and maybe to sort them by popularity. Obviously, comments are welcome but this is not the place to criticise others mantras. Just because one doesn't make sense for you doesn't make it irrelevant for the one who shared it.
