For me, doing the Vicki Welsh treatment for fabrics is well worth the extra time and effort.
Even some "good/better/more expensive" fabrics have had very bad manners!
(meaning they bled, wrinkled, shrunk, or in some way were not nice to use.)
Also, I've had some/most of the older VIPs, Peter Pan, Marcus Brothers - some of the fabrics some people consider "lesser brands" behave beautifully - the colors were fast, minimal shrinkage and wrinkling - you did notice I said "most"
I have had some Modas that were bleeders or loaded with excess dye.
I do not seem to be smart enough to tell ahead of time which fabrics might be problematic. So they all go through the soaking/washing process.
But - I also prefer a flatter look - and - even if I liked the puckered look - I would prefer "even" puckers.
