@Stella_Leo At what temperature and how long did you cooking the baking soda? It would be nice to know for future reference. Baking soda is easier to find than soda ash. 🙂
I got some tie dye kits that were on sale for like $3 each( only had 3-4 colors though). Surprisingly neither had soda ash. You think I should try to diy it and use that to be safe?
@AwesomeGrl When you rinse your thread in the cold running water, a little dye will come out. But that dye is excess dye that did not get absorbed in the thread. So don't worry, the majority of the dye will still stick to your thread. The soda ash helps the thread absorb and keep the dye in. 😉
