Hi Viorica, To maintain the soft surface of the Melamine felt I never try to stiffen on top surface but rather 3 coats on inside allowing time to completely dry in between & prefer to use solvent based stiffener for this felt elaine
do you have any tips on how to deal with stiffening the brim in the case of an upturned velour or Melusine? I'm wary of the white marks or fading if I add stiffener there.
