Someone on another message board shared this idea for prewashing precuts....
Fill the sink with hot water,
dump in the charm squares, fat Q's or strips...
agitate a bit using a large spoon
squeeze out as much water as you comfortably can
place the wet fabric in a salad spinner and spin out any excess water
press the damp fabric with a hot dry iron or air dry...
This simulates a trip through the washer and dryer with out the fraying and hassle .
Neato!
