I wash everything but charms, because they would lose too much size-wise. I wash on gentle cycle, full tub of water, cold, and put a big towel in the dryer with the smaller pieces of fabric. They do pretty well. I've tried all the "tricks" to keep fraying to a minimum, and none of them work any better than the others. All fabric frays...period.

IRR stands for International Round Robin. If you search for "Abbreviations", you will find MANY threads that list them for you.

In the sink, roll in a towel to dry and iron.

Get yourself one of those laundry bags. They are made especially for fragile items that go into the washer. Beause of the way the bag is made (lots of holes) the items get clean but are not tossed about to get destroyed, all stays fine inside. I use the bags lots.

Don't wash - no problem then.

This works, I've been doing it for years. There's 2 ways to snip....
1. just cut diagonally across the corner, cutting about 1/2" of the corner off.
2. Cut into the corner on a 45º andgle, cut about 1/4-1/2"

This tangles all those threads together as they get loose so they can't unravel a few at a time.

I soak them in hot water and then put them in the dryer.

Why doesn't this work for me? I have a handwash setting on the washer and everything. So far pinking or serging works the best for me. I did treat myself to a pinking rotory blade. That has made things so much easier.

I do not wash any of my fabrics. I mostly hand applique and I have an easier time if it is unwashed. If it is necessary to wash the final product I throw a color catcher in the machine.

Most of my fabrics are rinsed in the sink and dried, no washer. I do use the washer when I have a lot of fabric to wash. I clip the corners but am not sure it does a lot of good. I think I will try the serger ides. I am in the middle of organizing my sewing room and am washing the fabric that has not been washed, so I am using the machine on a rinse cycle only.
I run batiks thru a full wash cycle using Shout Color Catcher.
