For those that prefer not to pre-wash, here are some of the things that MIGHT happen when they ARE washed.
The fabrics might bleed (the dyes in the fabrics)
The fabrics might shrink
The fabrics might shrink unevenly
The fabrics may become very limp and/or wrinkled when the sizing is removed
In my experience, these things can happen with LQS fabrics as well as fabrics from chain stores.
But hey, if you-all enjoy gambling - don't let me spoil the excitement and anticipation of the washing results.
