Our grandmothers (in Carnia) while wearing a "gerla" (basket carried on the back), not to be with idle hands, knitted (gugjâ). The iron less used, was leaning on the side, hurting them.
Thereby husbands, supplied them with an object of heart-shaped, embossed and engraved with floral motives, made of brass or copper, with a recess to support the iron. This heart was hung on apron′s belt.
