I have never dyed anything. I found it a little intimidating, but once I did it I can't figure out why I thought it would be so difficult. I did have to use an acid dye since the fabric I was dyeing was 100% nylon. I found the dye online at Dharma Trading Co.
I dyed it on the stove top in a big stainless steel pot. I didn't want to try it in my washing machine since I have a front loader and I wasn't sure how to go about adding it into the washer. Once I put the fabric into the dye it just soaked it up. Wow! It turned out exactly the color I needed for an upcoming Halloween costume. After it sat on the stove in the pot for 30 minutes I rinsed it several times and hung it up to dry. It turned out perfectly.
