Primo DK

From Plucky Knitter:

Most of our wool is considered superwash, and even for these we always recommend hand washing in a gentle wool wash such as Eucalan or Soak and then laying flat to dry. We pride ourselves on the luxurious fabrics that our bases create and due to the cashmere content in most, there are only a select few that we would consider machine washing (Feet Fingering) and even then, only with the most minimal agitation possible or even no agitation. When blocking or washing a NON-superwash, please be mindful to avoid warmer water temperatures and any agitation, as this may lead to the felting and/or shrinking of your fabric. 

When you do find the need to fully immerse a piece with several colorways, we suggest always creating a small swatch to soak first. All you need are just a few rows, no need to be in the pattern, just using all the colors. If the swatch does not bleed into itself, go ahead and bathe the full project with confidence. We have also had success using a Shout Color Catcher and/or a light vinegar rinse when immersing the various dark/light colorways together in a bath of cool water.
