Here are the finished prefolds:
(L-R) Bahama blue, Tropical green, Orange, Sunshine yellow, Lime green, Ocean blue (repeat)
Now for what I did:
I ordered 12 toddler and 12 regular. I bought a rainbow of Dylon and Tulip brand colors. I was told that they are fiber reactive and would not bleed or fade like Rit brand dye. I read the directions and it seemed a little excessive to mix the dye in a cup, and then add to a sink of water. So I just filled the sink and added the dye. Stirred till all the powder was dissolved.
Tulip red was more pink so I mixed that with Sunshine yellow to make orange
Then I added my prefolds. Set the timer for 15 minutes and stirred/swished constantly. Then reset the timer for 45 minutes and came back to the sink every few minutes to give the diapers a swish. Cambree said it looked like soup. lol diaper soup!
This is what they looked like right after they came out of the rinse cycle:
(It appears I forgot to take a picture of the orange diaper, oh well it was 4am when it finished)
