1. Do I use detergent?
2. I have half to full yards - many of them. Can I wash like colors together?
3. How will I know if they have bled out all they are going to? Do I have to keep checking the rinse water?
4. Do I put it on a full cycle or just rinse?
I wash and dry mine as they will be handled when they are done. Then you know if there is a problem before you do all the work. I have never used color catchers, but they sound like a good idea.
