Washing fabrics before cutting and using starch/sizing
I like to know how my fabrics are "au naturel" before using them.
I think of starch/sizing as "scaffolding" or "foundation garments" - when the foundation garments come off - things go back to "how they were" - which is what happens after a piece of fabric that has been sized/starched is washed.
If it is too "flimsy/loosely woven/thin" to use before it is starched - it will still be too "thin/flimsy/loosely woven" after it is starched.
I will concede that starching/sizing can be useful at times - but - it still can not make "poor quality" fabric into "good quality" fabric.
