When I was at a sewing class I poked my finger with the needle and got blood on my project;not alot but enough to have it spoil the area. Anyway, a lady told me if I used my own spit on it (place the soiled part in my mouth and got it saliva wet, it would removed the blood. IT WORKED. However, this cure will only work if it is YOUR blood on the project and YOUR saliva taking it off. I hope I worded this correctly. Enjoy
