But, do you really need to separate everything before sticking it in thewashing machineand selecting your cycle?
The short answer is it depends.
How to separate laundry right
Most people start sorting laundry by color.

You don’t want towels in with lighter fabrics, as towels can be abrasive against other items.

In the same vein, heavier fabrics might not dry enough and come out of the dryer damp.
That can lead to an unpleasant, moldy odor.
