I am going to try making a lap quilt, so I want to prewash the fabric so it shrinks before I use it. I plan to use hot water. Here are my questions
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?
Thank you! Virg
