If you enjoy breaking black, you'll love breaking food colors such as purple, violet, aster, delphinium, juniper and others.
becomes magenta and purple with a tiny bit of sky blue.
Wilton Purple (very hard to find) or AmeriColor Regal Purple
Becomes purple royal blue and sky blue.
The green brown is more of gingerbread than shown here. The red brown fades into pink.
Alternate step 5 - Lower both hands so even more of the knitted blank sinks into the dyebath. This will create a pattern Violet and the Aster Mauve with the red in the center and the blue on the edges.
Second Alternate step 5 - lower just one end of the knitted blank into the dyestock in step 2. As the red bonds, drop more of the blank in to bond with the blue.
Because the acidity of tap water is different, I can't tell you exactly how much vinegar to use.
In my case, 1 teaspoon of vinegar in 8 oz. water sets red and between 1 and 2 tablespoons sets most blues.
If you don't know your ratios and you only have one blank to play with, I'd suggest you add the vinegar 1 teaspoon at a time and wait at least 5 minutes before adding each additional amount.
Yeah, it's slow.
But if you add the vinegar too fast, the red is going to bond to your pot rather than your yarn.
Knitted blanks can be purchased online.
Or you can recycle sweater sleeves like I used for the photos. Look for sweaters with some wool, animal fur or nylon. The greater percentage of these fibers, the darker the colors will be.
Sweaters with some cotton or acrylic are fine. However food color will only stain cotton, not dye it permanently. Acrylic won't take color at all.
You can also knit or crochet your own blanks. The looser the finished fabric, the more the color can soak in.
Note: stitch patterns with bumps dye with very nice halos.
Wilton Royal Blue will also work for this project, for sure.
The following colors may work but haven't been tested: AmeriColor Navy, Electric Purple and Forest Green.
McCormick Electric Purple.
