I have used salt and vinagir in the past,but find the color grabbers are better if you have several new farbrics and they are all different colors. The salt will set color, but not keep it out of hte wash water and I never wash quilt frabic befor using. I like the effect you get when the batting shrinks and the frabics "puff". I think all of us have a different way of doing tha suits the sewer and that is what makes our quilts "ours" and not factory produce.
Now I have a question. I have several children who are wanting me to teach them to sew. 1 boy and 3 girls so far, all my grands. Does anyone know of any good books aimed at very young sewers? they are all 8( it was a very busy year in my family) I enjoy the forum and all the infomation I a have gotten by reading and chatting.
