Many colors (especially reds) may run. How do you set the color to prevent running?
I have needed this advice.
You can use Retayne to set the colors in commercially dyed fabrics. It’s available at http://www.dharmatrading.com.

Retayne is great. I used it on my red towels and the color was finally set.
