I'll keep an eye on it as I'm allergic to mold. The iron is spotless and the ironing board cover is soft. I did stacks last night and more this morning of triangles by just spraying them and pressing immediately.They had been sewn and ripped out and I didn't want the bias edges distorting. It worked well for me. I have more of two of the fabrics, but not the feature one so I couldn't just start over. I don't use anything on my freshly washed fabric - just press it.
