If you look at the top of the picture, there is a clear clip. I put the picture in and clip it shut. There is one to go at the bottom as well, although I didn't put it on the picture.
I didn't get them all out to try (I may regret that later), but just went ahead and packed everything away. My fireproof fabric is in transit, so I hope to have pictures to show of that by the end of the week.
