I would wash it - but I was everything washable before I cut it now.
I *think* that the perma press is preshrunk (the bolt label is not entirely legible), but I noticed that their website says the perma press should be a cold wash on delicate cycle and low heat to dry. Not what most of us put our day-to-day quilts thru, lol. Since I do have scads of the muslin, I think I may do a few test washes/dries at different temps and see what happens.
