If you're in the gym and trying to lift something heavy, odds are you need a spotter. Even if you fancy yourself to be a big strong macho man (or woman). You may think you can just do it yourself (and maybe you can), but wouldn't it be safer to have an extra set of hands to yank that weight off your chest if you try to bite off more than you can chew? Perhaps you and your silly pride can struggle through it, but odds are you're going to have bad form; the sloppy reps just aren't going to deliver the results you were hoping for. Creating a piece of artwork is no different. Sure, you can do it all by yourself and get something done, but it's always a good idea to find an artwork spotter to have your back.
