How to soften scratchy & itchy wool yarn
Not all wool yarn is created equal. The softness of the fiber has so many variables, from the breed of sheep to how the fiber is processed and treated. In addition, wool fiber has scales just like human hair, it can be fine or corse with long or short lengths. Any of these variable will impact whether the yarn feels scratchy, itchy, or prickly agains the skin. Did you know that gently washing your finished project can really have an impact on the softness of your finished project? Now, it's not going to turn a rustic wool into cashmere, but it will soften the fiber and allow it to bloom thus providing the best version of that particular yarn.
How to Wash Wool to Soften It
We'll accomplish this by giving it a full wet blocking (aka a good soak). It will allow the fiber to relax and bloom showing off it's full beauty. Wet blocking will also even out most minor stitch imperfections, too!
