The other day, I did some immersion dyeing and did not like how these two folded pieces turned out. My brown dye ended up very pink (it was very old dye).
I decided to over-dye them using low-immersion dyeing, but scrunched them, instead of folding them. I put 1 cup of Procion Olive Green (2 tsp in one cup of water) added my scrunched damp fabric, then poured in 1 cup of Procion Golden Yellow (2 tsp in one cup of water). I let it sit for 20 minutes, then added my soda ash water (3 tsp soda ash dissolved in one cup of water). I let it sit for 2 hours, then rinsed the fabric out. I should have probably waited a bit longer, but still like the results and it is a huge improvement. I would definitely cut these into smaller pieces, as I still don't like how strong the line pattern is from the first dye.
