I need some input on mixing wools. If I spin yarn for socks. If I do it in different colors so I can do colorwork. Do I have to use all the same kind of wool from same sheep? Can I mix and match my fibers? Can I use brown BFL and white Corriedale and even some colored fiber throwed in? Spinners please help out with this. The yarn I make would not really all have to be the same size right? Suggestions Please!!
