Don't confuse sodium bicarbonate (baking soda) with sodium carbonate (soda ash or washing soda). They are completely different. Sodium bicarbonate will give you a pH of only around 8. Sodium carbonate will give you a pH around 10 or 11, which is what you need for using Procion MX dye on cotton and other plant fibers.

Most swimming pool suppliers do sell sodium carbonate, but I too once had one try to substitute bicarbonate for what I wanted. Don't let them sell you the wrong thing. Look at the fine print near the bottom of the front label.
