This is a very easy DIY and so inexpensive. One wall in our bedroom is painted dark chocolate brown but I had a hard time finding an art that would go above the bed.
This is a before picture (what was I thinking?):
I searched Pinterest for an ideal art to go on a dark wall and in one of my searches, I came upon an Ikea RIBBA white frame with a black and white photo. It was very simple and I knew it would complement our brown wall. However, the cost of the RIBBA frame was $20 and I needed 2 of them, so that will be $40 and I could get a finished frame for that cost. I stumbled upon the NYTJJA frame which was only $8 but it didn't have a mat but I figured I could make one.
I bought a poster board for $2 and made my own mat. I then used our engagement photos to go into the frames. The total cost for the whole project was around $22 including the pictures.
This is how the brown wall looks now. It is not the best picture with the sun reflecting back but overall, it came out the way I wanted it to be. Much much better actually. The frames pop on the wall and the best thing about the frames is that its about me and my husband.
