It depends on what kind of fabric... silk or brocade I would DRY CLEAN ONLY. The reg fabric (general prints) like amy butler or a celtic print or any other print that isn't a fanciful freehand type
I would wash cold and hang to dry if you are afraid of shrinking. I did pop mine in the dryer and it turned out fine. The tag on one of the Amy Butler prints I got here at Attached To Baby says MACHINE WASH COLD- COLD RINSE LINE DRY
Good luck!
