I wash in Very hot water -- usually by hand and then pop it into the dryer with a large towel. If I wash by machine I do it on delicate. Fabric does shrink a bit. And I hate the smell of most new fabrics.
Especially if it is a dark or red fabric. I once make a red and white quilt and didn't wash one of the reds. It ran just enough to spoil the contrast
