Low water, uneven dyeing, and making it work! 
Take a skein of yarn that has a color you’re not crazy about. Do the vinegar and water thing. Put it in a crock pot and cook it with Wiltons Food Coloring. But, don’t take my word for it, go to the Christ, Coffee and Knitting Needles Blog for the instructions:
Fall will be here before we know it, and that means there are holidays coming right behind where we might be entertaining at home. It’s always fun to have a hand knit touch in your home for other people to see, and if you’re going to be in the kitchen all day you might as well have some nice knit dish cloths to use.
Thanks! Feel free to link to ANY of my tutorials!
