There are stiffening solutions out there. Been along time but I think I used white vinegar solution. If you use a solution that has a glue or starch base to it, I found it best to use wax paper to rest on. it won't stick to the wax paper. Or let it rest on a small screen. I use to stiffen witches hats and the lace I used. I use to make hat stands as center pieces or decorative pieces through out.
