[QUESTION] Guitar Display Tips?...

Hey friends,

I'm in the process of building my home studio, and I'd like to display/hang my guitars. My issue, however, is that I live in Wisconsin, which has varying temperatures throughout the year (November - March being the most concerning). I was wondering if anyone had any tips for keeping my guitars healthy while also having the benefit of having them out of their cases? I'd like to avoid purchasing a humidifier if possible, but I also don't want to damage the instrument. Any advice?
