Throw it in the washing, throw it in the dryer. Just like what will happen when it is used. I do not make show quilts, (no show would accept me LOL) only ones I want used and loved. All have written directions to wash and dry. One thing I do, that others may not, after washing and drying, I hang my quilts over the banister/balcony for 24 hours just to make sure it is good and dry. LOL usually not a problem in AZ, just hang-overs from living in the the humidity of the South.
