If you're doing tie dye, put the soda ash and your undyed cloth or clothing into a bucket of water together BEFORE you dye your fabric,. This prevents the colors from running like they would if you did a soda ash bath after your cloth was already tie dyed. This product works insanely well. You just need to use it right! (If you're not doing tie dye, but instead you're just doing a dye bath where you fill a bucket with water and dye, you can add soda ash later and it's no problem)More review and tips on how to use soda ash belowI've been using this soda ash for about a year now. It works REALLY well, pretty much any color you dye stays put after you rinse out the dye. Can be added to dye bath immediately or later depending on preference. Both methods lock in the color. I haven't tried this with natural dye, but I know that with MX dyes or RIT dye this works perfectly. You don't need a ton of it. maybe a quarter to half cup per medium sized (about a foot tall x foot wide bucket). so if you're not dying a ridiculous amount of yardage this bag should last a decent while.

Good for delivery and packaging.

Perfect for tie dye projects, I got pulled over and searched and the police officer was wanting to know what was in the bag I informed him that I was on my way to do tie-dye lol it was kinda funny. Like dude don't waste your time

Just learning how to different tie dyes when I accidentally bought this thinking I needed it (when I didn’t) but then as I tried other dyes, it turned out I did need it.I will be buying more soon. Turns out about a cup makes a gallon of or pre soak so depending on how much you do, this will be more than enough or you may need lots more.I keep mixed portion in a five gallon bucket with lid to save so I can come back to it. You can apparently sprinkle on at end of process to but still just working on one process at a time.

Fast shipping. Exactly what was ordered.
