First thing I would try - put it in the washer - DRY - and see if it has room to move around in your washer.
Second thing I would try - put it in the dryer - AS IS - and, as Prism99 suggested - see if there is room in your dryer for it to move around freely.
IF your washer and dryer have "move around room" - If it were mine, I would wash it on a gentle cycle - with color catchers - with a "mild" detergent, then dry it on a "until done" with "medium" heat. (My "old" dryer has three heat settings)
Because I am in the confirmed "soak in hot water and then wash before cutting" group - I forget about using the color catchers.
Even pastels can have excess dye in them.
I am also in the "it should survive a gentle washing and drying" group.
