How to Set Yarn Color

There’s nothing worse than pulling a knitting project out of your wash basin or washer and finding that the colors have dulled or that one color bled into another. That project you worked so very hard on now looks lifeless or silly. Setting yarn color can be an important step in keeping one project from ruining another project or other clothing. Setting the dye color in yarn will also keep your projects from fading, so those bright orange socks that you knit will always stay as vibrant. Many yarns, especially cotton yarns, will bleed color if the dye is not set properly. This means your project could dye your skin, other surfaces it is in contact with, or other projects it is washed with. Bright and dark colors, like red or navy blue, are the most likely to fade or bleed. However, any yarn color could fade as it is used and washed. Of course, following your yarn care symbols carefully is a must for proper care of your knitted items, but there are some other things to try to set your color. Below, we give a knitting tutorial for the “safest” way of setting your yarn dyes with vinegar, but it may not work for all types of yarn. You may have to experiment with different methods to see which one works best on your yarn, but, of course, use test swatches, not finished products! It is safe to start with this method, though, and if you need to, you can always give something else a try. A few of the other techniques are also explained below.  Make your bright projects shine by setting the dye! For more great projects like this, subscribe to our free email newsletter!
