The idea behind Heli MG Eco Faux Fur Caps is, in addition to the 'fur' being animal and environment friendly, that they are made with as little amount of new or synthetic materials as possible.
I buy tweed or Merino-wool caps in immaculate condition from the charity shops. The hats are washed properly before proceeding to the making of new product and their lining and trimmings are carefully stripped.
Then I tuft them with traditional tightly twisted rya yarn which is 100% lambswool.
And for the last I re-build the lining with lightweight silk/cotton satin fabric and attach the trimmings and the care-label.
