We used it on the beach then took the shirts home to set and wash. Over all lots of dye and worked out nicely . Did 7 shirts and had lots left over . It was easy to use, the colors were very vibrant. If they came out muddy, that was our own fault. Value for money, I think was fair. Washability is fine.The soda ash should set everything. We did use saltwater because we were at the beach. So I was reading that that would act kind of like a soda ash, where the colors would set almost immediately. Bottle size seems small, but it makes sense 41 packet of dye per the bottle filled.Then you have the extras where, once you run out of that bottle, you just fill it again.I don't see that as an inconvenience and it reduces waste

This was so easy to use! Absolutely perfect! And the shirts turned out great! Each packet did 3-4 shirts depending on how much of a color was used on a shirt.

This kit was amazing to use! I tie dyed t-shirts with my 3 grand kids. It was easy to use, the instructions were clear, and everything came in the kit. Best is there’s left over dye, etc. for another time. It was a fun activity with this kit. Highly recommend!
