I use the $1 a can heavy spray starch most often, I hang the fabric over a rod and spray it. I have tried the bottled, but I have to mix it heavier than 50-50 sometimes to get the same effect.
I starch after washing and drying the fabric and then cut it.
Some fabrics like muslin doesn't like to stay as stiff, so I will respray it as I work with it if I feel like it needs it.
I am working on a EPP project, that fabric is as stiff as cardboard LOL but when the papers are removed, it holds it's shape perfectly without having to be pressed. :wink:
I will have to try that, maybe move my rod to the bath tub LOL
******CAUTION****** I used to have the rod over my tub, but one time I forgot to clean the tub before showering and the dried starch was VERY slick when the water hit it. It was like a very slippery slip and slide!!!! That was when I moved the rod and bought the shower curtain to place under it :D:D:D
