It’s a little lighter than I’d envisioned, so I’ll definitely have to try again. First, use non iodized salt and soak in salt water, hopefully this will help the take better. I’ve also read about people soaking the fabric in vinegar.
Also, and this is kind of a biggie in crafting in general and often cooking, don’t experiment on your first go at something. It makes it harder to pinpoint the ways you can improve in the future. I mixed two colors – emerald green and turquoise and I wish I’d just tried one or the other now. maybe for the rest of my rug that’s what I’ll do, with stripes of this yarn!
Anyway, I’m mostly pleased with the result, so I’ve written up the steps I took in a yarny recipe.
dyeing tee-shirt yarn
non iodized salt (I think this might be part of my dyeing problem, I only had iodized.
cold process, fiber reactive dye (I used mx procion dye)
a big pot or tub
tee-shirt yarn (see my tutorial)gloves and mask
- don gloves and mask
- soak yarn to get it wet all the way through
- fill tub with enough cold water to cover yarn, 3-4 t dye, and 2 cups of salt
- stir for 20 minutes
- add 1/3 cup (or 1/3 cup per 3 gallons of water) soda ash dissolved in water
- stir occasionally for 50 minutes
- rinse and wash yarn till water runs clear
