I always wash everything washable before cutting it. Including the battings - if they are washable.

This includes trims like bias tape and rick rack. I would probably wash cotton thread if I could figure out how to do it.

My quilts still get "some" crinkle in them after they are washed.

I would no more knowingly use unwashed fabric than I would not use my seat-belt while traveling.

There are many that are adamant that there is absolutely no need to wash anything before cutting it.

I agree that it is a "bother" to wash, dry, and fold that yardage. I also think it is a bigger bother to deal with something that shrinks a lot or bleeds after it has been sewn into an item.

I"m not smart enough to tell by just looking what fabric will do what.
