What a lovely feeling it is to finish a project! I've just put up a collection of pictures in our previously boring front entry hall. I chose one photo per year since our wedding in 1997, with the idea that this tells the story of our family's growth. I collected frames that I already had, added some more from thrift shops, and spray painted a bunch of them. It's the crazy quilt approach, and I think it works.
I've positioned the whole thing a bit high, for two reasons. One is to leave room for another row of pictures, and two is to keep it out of toddler reach.
