I wash fat qtrs. in a dish pan of hot water and rinse several times. Use the salad spinner to get rid of the water and press while wet. Takes care of bleeding and shrinking. All big pieces of fabric I surge the edges or zigzag them and in the washer and high heat of the dryer. That was there will be no mishaps. You never know how someone will wash their quilt once it has been gifted, so I do the worse that they can do,
hot water and hot dryer.
