Pressing a customer supplied garment is always tricky. We take no responsibility if the garment gets damaged.  If we supply the garment and mess it up,we know where to get another one.  Most of the time when someone supplies you with a garment it is because they got it on sale somewhere and the quality is not always able to sustain decorating. If you insist on supplying your own items, before we put any design on it, you must sign a waiver absolving us of responsibility in case the item doesn't turn out the way you wanted.
