Using old picture frames to hang photos ‘out to dry’ is a great idea. Large old frames can be gotten cheaply if you do not have any from yard sales and thrift stores. You could paint these all the same color or use them as is. Using twine or clothesline string several lines across the frames width. Using small clothes pin that can be purchased fro Amazon or Michaels/Hobby Lobby clip your favorite photos up. You can change them as often as you like.
Something so simple that even a child could do… and your child would be delighted to make this and give as a gift or to plant a little something to put in the windowsill to grow. (Think herbs or long grass) The clothespins could be glued permanently on and they could also be painted before putting them on or spray painted after they are on. Here a tuna can thoroughly washed out was used.
