I used stretcher boards for this project. They are SUPER cheap. They are meant to be used to stretch a canvas, but they worked really well for this project. The size I used were 40 inches tall by 16 inches wide.
The frame ended up costing me less than $10. I put them together and then filled the corners with Spackle. After the Spackle dried, I painted the frame with some paint that has sand in it. LOVE it!
For extra support, I stapled a few pieces of balsa wood across the back of the frame. One on the top. One in the middle, and on across the bottom.
Then I matted several sepia toned wallet photos. I used ribbon and clips to attach the photos on the string. I added a couple of embellishments and VOILA! I had my priceless work of art.
Have fun creating!!! :)
