Here is a shot of my trusty dye bottles. I have had them for at least 2 years. It is probably time to get another set, but they seem to be holding up okay. I always try to put my dye bottles on top of the dye container so I know what color they are, but much to my surprise the print on the labels has disappeared! Many of the containers are a mystery to me. Note to self: use permanent marker to label containers, and keep marking them each time I use them.
Below you can see all the colors of dye oozing out the sides underneath the plastic. It always looks really cool to me.
I always use more yellow than any other color.
