Woolfiller – dealing with holes

WOOLFILLER repairs holes and hides stains in woollen jumpers, cardigans, jackets and carpets, for example. How? By embracing the specific character of wool. The fibres of wool contain minuscule scales that open up when they are pricked with a felt needle. The open scales bind together and cannot be separated. Not even in the wash. Woolfiller can be used with a machine or by hand. It is simple, sustainable and satisfying; a new solution for an age old problem.
