I love typography. I always have. Maybe it's the years of writing thank you notes when I was a child, maybe it's my years of art training, maybe it's that I secretly hope having letters and type everywhere around the house is a subliminal reminder to my family that they should be reading. I don't know, but I love it.
If you'd like to display your art and boss your children around at the same time, good resources I've found for this type of art are Keep Calm Gallery (thanks, Melanie, for the tip!), Concrete Hermit, Typographic Posters. Go wild. You may even find one that says "I'm not going to tell you again: clean your room."
