Hey guys, I'm a beginner (made few cushings before) and was offered to reupholster full car seat with vinyl. The bottom part took 8 hours, the backrest almost 12 hours, and it looks terrible. I will try to make it again. I know what could be possibly wrong, but do you have any tips or tricks to do it faster and cleaner? What tools make a big difference? Is it normal to spend this much time on it? All advice and criticism welcome!

I have an update! Check below
