Freelancers in DFW — where do you actually work from?

I do freelance graphic design and I can't work from home anymore. My apartment is too small and the walls are closing in.

I've been bouncing between coffee shops but I feel weird sitting there for 4 hours buying one coffee. And the wifi is spotty.

Are there any affordable coworking spaces in Dallas that aren't WeWork prices? Or do people just use libraries? The Dallas Central Library downtown looks nice but I've never tried to actually work there.
