The butterflies are larger than I expected and they cover enough space to make a lovely wall accent. This would be great if only they actually secured to the wall. They come with the adhesive strips already attached. I cleaned the wall and waited for it to dry. Then I put the butterflies on the wall, pressing and holding firmly to secure. An hour later there was a loud clatter as one had fallen off the wall. I put it back up. Over the course of the next day about 4 fell off the wall and I kept reattaching them. They fell again. I've had these butterflies for a month and I've given up on attaching them to the wall so I have about 5 butterflies laying on the floor. I'll have to find a better way of attaching them to the wall and once I've got that worked out they're going to be lovely but it's a drag to have this problem. Please do not put these above your bed or anywhere you might be standing when they fall! They're sharp and that could really hurt.
