I like to wash when I bring it home as there are many chemicals in it especially formaldehyde, I have a rotary cutter with a pinking blade and to trim the edges prevents lots of fraying I do use the washer gentle cycle --hot then hot dryer I remove from dryer immediately fold and do nothing else until I am ready to use it I have not washed anything smaller than charm packs but anything from quarter yard down I hand wash and air dry
