This is one of the ways I do hand painted 100% angora yarns, there are many ways to hand paint but this is my preferred method, first I place the skein on a basin with a vinegar water blend, one gallon of water to a half cup of vinegar, then I take the skein out squeeze the water a bit and place the skein on glad wrap and using a small paint brush, I start to paint the skein.
Being careful not to place the colors too close to each other. I choose the colors that I like to do the skein in as shown below. Microwave for 5 min. on high, then flip the skein and paint the other side and microwave again then I wash the skein and block and dry.
