For Christmas and my birthday I like to hang my cards on a vertical piece of string down a wall. I use paperclips on the string and it's hard to get the clips on so they and the cards don't just slide down. These tiny clothespins do a much better job, and the twine looks nice. I love the colors of the clothespins. They're a bit hard to handle just because they're so tiny, but so far I've only broken one. I had one small problem with the twine in that I couldn't find its starting end.
We used these for a lovely photo display at my parent's anniversary party. And since then I've been using them to hang children's Sunday School art. They like to hang their own pictures. They sometimes break but they aren't really made for many uses. Just for once or twice.
