Citric Acid vs Acetic Acid (vinegar)

I am not sure if I liked using the citric acid. I mixed two 8 ounce cups with warm water, the appropriate number of food coloring drops and 1/4 tsp of citric acid. First off, the color didn't look right, like it washed out the red drops I used. When I poured it on to the presoaked wool, the color instantly went on the wool and the water was clear around it, before heating. I had to make 3 times the amount of dye bath. I am heating it now, but the color isn't purple it's blue even though I added pink. I was so freaked by the instant absorption of color too. I am using a natural heather merino wool. Pics later. I promise. Darn, I was so looking forward to not having the vinegar smell!

This was all the same "dye lot", it just pooled strangely. Is it because of the wool type????






It looks fine, but I needed a specific purple for something for Elena, so back to the dye bath.

This time I used 3 packets of Kool Aid Grape, some water, glug of vinegar and Knit Picks Wool of the Andes and viola! Not quite the deep purple I wanted, but at least it's one color!

When I tried using purple Kool Aid, it didn't come out rich and deep either. Mine looked pretty awful, almost like a washed out grey.

Hope you're feeling better! :)

Somewhere in blog land I read a blog on dyeing purple. I think it is hard to get a good one as red is very unstable. In my last dye experiment, I made the dye look black. When I painted it on the yarn, it looked black. It wasn't until after I nuked it that I got a pretty purple.

I believe that I took a Grape KA and mixed blue and red food coloring in with it, until I got this terrible black color.

I think the yarn is pretty how you dyed it.

I kind of like the pooling pattern. Would be interesting to see how it works up.

Grape Kool Aid is the only consistent food coloring purple for me. Wilton's violet splits, but it does better when mixed with brown or black. :-) Of course, the *real* protien dyes are much more likely to give you the color you are looking for.

Glad you are finally dyeing...sorry you are having citric acid troubles.
