Starch/Sizing
I will use it - occasionally -
But I still want my washed fabric to have enough body to "stand up on its own" without NEEDING the starch/sizing added to make it "substantial enough to use."
I think of starch/sizing like Spanx or foundation garments - remove the garments and the body goes back to how it was - wash the item and the fabric reverts to how it was without starch/sizing.
