dyeing (similar to roving/top/sliver etc.) is also a tricky bag as to what to call things.
first of all, there are an infinite number of ways to dye. in this instance, we’re going to ignore the hand painting methods because i don’t do that. that said, i believe that kettle dyeing is when you put the fiber in the water and then add the dye to the fiber. in immersion dyeing you mix up the dye in the water, then add the fiber. so. hot pour dyeing would be a form of kettle dyeing when you pour the dye onto the fiber while already heated. i often do an immersion dye and then hot pour over the top of it. mix and match ;)
in general, i do not pre-meditate my colors while dyeing. dyeing for me is the ultimate in playing and seeing what comes out is the joy of the occasion. i have a natural sense of color that i rely on for most choices. sometimes i push myself beyond using my knowledge of color theory or some other bee in my bonnet. sometimes these turn out and sometimes they don’t. if they don’t, over dyeing or (for roving) hand/drum carding is their destiny!
in both dyeing and spinning i am first and foremost a knitter. that means that it is of the utmost importance to me that i am able to knit with the yarn coming from these rovings and that i like what it looks like when knit. dyeing is only half of this equation though, the other half occurs in how i split up the roving to spin and in deciding how fat or thin to make the yarn.
