I have been experimenting with Paverpol fabric hardener, hoping to create some large outdoor 'garden art' flowers. Here are two large poppies that I made.
I had to put reinforcing wire in the petals, between the layers of stiffened fabric, as they were quite large. This was good because it meant the petals could be bent into shape but very time consuming to do. I also needed several coats of paint to get a solid red colour. Unfortunately, this idea is not realistic to continue for selling.
These are some small practice flowers I made first, with the idea of upscaling. After my experience with the poppies, it will not happen.
