One of my favorite inexpensive art tricks is to use words as inspiration. I mean, I was a Creative Writing major in college...
Like my stenciled art I did for my living room, this photo from Domino shows that the "text" doesn't even have to be legible to count as art. Sort of a "text goes here" filler squiggle. But it goes to show that anything done on sort-of nice paper and put in a nice frame can work as art in your home, especially if it has special meaning to you. Here's some ideas...
Written words to feature as art in your home
A favorite poem
Part of a love note from your significant other
A song lyric
A movie line
An inspirational quote
A nursery rhyme
Something in a foreign language you've always wanted to learn to speak
Passage from a favorite novel
"Commissioned" art by your kids
