Here's what I did:
Can you tell I am desperate to use this somewhere?
Two 5x7 frames that I unearthed while unpacking
Take out the glass or acrylic and trace the size. Quick and easy.
This project is great for the budget conscious, in need of something to fill a space, or add pattern, or perhaps pull in a color or theme or color and theme. I'd have loved to use fancy frames and paint them all purdy, but in lieu of the "big picture", these worked for me. Now, to finish the collage wall so I can share it!
Total $$ : ZERO. If anything, the frames were about $2.00 each (maybe) from IKEA.
Total time: Less than 1 hour.
