Pressing flowers in PVC

With the flowers I pressed on the calico, I decided to press them between pvc to see the effect I would get, I do really like this effect I think it is really intresting and fits my theme really well, the only thing I would say is that I didnt let the flowers dry out probably and also didnt have the equiment to do that, so when I pressed them they caused abit of condinsation and the flowers have started to go mouldy and smell, so I looked int using fake flowers as they would stay perfect forever, and I got the same effect. So if I am to use this proccess I will use fake flowers.
