I recently tackled a project that cost me nothing other than a bit of time.
In my college Photography 101 class I did a project that involved shooting (and developing) a series of photos. I did my project on "Old Montana" and had fun shooting relics and landmark buildings as we drove across the state on a road trip.
The photos aren't anything to brag about, but they are meaningful to us and worthy at least of the cheap frames I bought for them a long time ago.
To make the collage a little more interesting, I added a couple of quotes that related to the "old Montana" theme. The letters came from an interesting novelty item I thrifted awhile ago. It is a box of letters used for old-time movie titling, complete with adhesive and a black felt background. The box sits on my craft room shelf, and even though I thought it had artistic merit on its own, I thought it would be fun to actually do something with the letters.
I tacked the letters up with glue dots, so they can be easily changed if I tire of the phases.
I'm happy with how my little vignette turned out!
