This is just one example. She ended up with enough dye to do 5 shirts! Four for herself & one for me. Mine is much paler than hers. I learned that the soda ash really makes a huge difference in the brightness of the colors. All the other shirts got soaked in the soda ash to start with, but mine was kind of an after-thought when she realized she still had some dye left & didn't want to waste it. Which is fine......I really like mine......but we were just amazed at the difference in the color intensity. That's GOT to be a science lesson, right?!
