so this several times! This will give it enough stiffness to be handled but not too much to lose the essence of the FSL, It should still look delicate. If you iron the piece it may flatten the threads! Also I use the stiffener just in the small areas that need the support. I use a childrens medicine syringe to dispense the stiffener instead of soaking the whole piece. .Be aware that no FSL’s were harmed in this experiment!
