A friend of mine found a quilt top (small nine patch scrappy blocks)at a garage sale. It is sewn very nicely and about the size of a queen, although I would like to add a border. But it has obviously been kept in a trunk with moth balls. The smell is VERY strong. How do I get rid of the smell? I will have to do that first before I can work on the quilt--or I will be blowing my head off!
