The initial steps of tuft-setting are the same as for burling: secure matching yarn and remove the damage pile yarns to create a bare area. After that apply a clear-drying, latex-based seam cement on the empty spot with an absorbent cotton swab. You will right now need a tuft-setting tool, when this is not available, a thin nail bed punch or a thin lower nail may be substituted. Standing a loop of the wool in one end of the bare area and insert the tool against the U-shaped underlying part portion of the loop. Travel this U-loop portion in to the carpet backing with a incredibly light tap of a sort against the top of the tool. Steer clear of a heavy blow, since this may force the pile tuft through the fabric. Even worse, a strong blow can distort the backing into an bigger hole that would prevent the common tension in the backing by holding the replaced yarn in the carpet.
