Hi Jeff

Very nice job, I enjoyed your article. I can remember growing up on the farm and how my mother and grandmother would use different natural items to dye just about anything that would take a stain. They also used onions and many of the other items you listed plus a few more. The wool you stained looks great. I really like the colors you got. I know it will make killer flies. I could be wrong but I don't think Alum would really be necessary for dying wool. But I don't think it would hurt anything either. I've done some natural tanning of hides with the hair left on and I was always told the alum was needed to keep the hair from slipping or falling out after the skin was tanned. Using too much alum does seem to make the hides very stiff. Keep us informed of the flies and how the fish like your flies from onion skins. Thanks for an interesting article.
