Create It Yourself
My guestroom needed a little something. It has been neglected since I never use it.
I used blue tape to create a grid on the wall. If you get 1 inch thick tape then that can be used as a spacer between the photos. Put two long strips on the horizontal and vertical center, and from there use small pieces of tape in between photos. Make sure you use lots of double sided tape so the photos don't fall...I've had to redo my wall because I didn't use enough tape.
I didn't want any sort of permanent fixture, because as more photos were taken I wanted to switch them out. So, I may end up putting photo corners on a poster board and slide the photos in that.
All of these photos were taken with my iPhone using Instagram or Hipstamatic. I love these apps...any time I can have the look of analog, I'm happy!
