You're going to Austin!!!! OMG I do hope you are as fastidious with posting while you are there. He is so amazing. I'm watching all of his videos for a second time and have an even greater appreciation for his generosity and talent. I feel I have a kindred spirit in you as I also love to have many paintings going on at a time. It is lively and vivacious and brings me much joy. I hope it also gives you joy and thank you for always keeping us updated with your progress - and you moved the date up!!!!! YAY!!!!
Hey @rudayo Welcome to the forum. You will get so much helpful information here - I agree with @Summer and @broker12 . I have a lot of experience with trying to finish dry paintings (I have what could be considered a problem in that I start and don't finish immediately a lot of paintings) - I'm not sure the size you are dealing with but a lot of people just use a spray re-touch varnish - spritz and carry on - I can't remember the brand as the thread it was mentioned on is now gone. I usually use liquin with a quick rub as I have a ton of liquin - linseed oil is beautiful but I have to always be careful not to add too much - I have to kind of scrub that in - I'm sure there are many more ways to skin a cat.
and I was missing a ton because I never knew the magic of "recent discussions" button - I kept going to the post your paintings to see what people posted - very rarely did I look anywhere else. I have to say, I think it is amazing that Mark Carder provides us such a wonderful venue for sharing and learning - it is incredibly generous of him. And to @Flatty for keeping it civilized. This website is much more sophisticated than most and allows for so many beautiful images. I was away for a few weeks so missed so very much. I look forward to catching up and getting in the groove of painting again.
I have always thought of UB as the warm blue. When I need a more warm blue, I will always go to the UB. It is tending more towards red and the others more towards green on the color wheel - I was taught that blues tending to the red side are warmer than the ones tending to more green side. I think that warm and cool relationships are extremely important and helpful.
