I started using flowers in my layouts a while ago and I was saddened to see them flattened after the album was closed so I thought of placing foam dots under each petal but, sometimes, they would show which I didn't like so I came out with the idea of placing a dot of glue with the glue gun and let it dry for a while. It becomes hard and keep the petals shapes. As it is clear nobody can see the dots and no matter how hard I press the album the flowers never get flattened.
