Then wash as usual by colour family. As you remove each FQ you may have to snip off any long hanging threads. Then throw into the dryer.
Pinking does several things: it eliminates most or the worst of unraveling threads and it makes it easy to tell that its been prewashed.
BTW, I pink all my fabrics before washing for the same reasons. Use an old cutting mat: the pinking blade is a mat killer even on self-healing mats.
Thanks for the info on the pinking blade, I use it to make the tie off blankets, I'll know now to use the back of my mat.
