I've been wanting to try tying a Polly Rosborough pattern, called the Blonde Burlap. It requires burlap which has been bleached to a lighter shade of brown, almost white. In his book he suggests Hydrogen Peroxide, tried this and it did nothing? In Gary Borgers book, Naturals he suggests using Clairoxide and I can't find this? Any ideas on the best way to bleach fur and hackle?
