Abstract: Looped tufts of yarn are drawn through proximate openings in a foundation fabric from opposite sides of the fabric and are intertwined in pairs to form square knots that secure opposed tufts of yarn to each other and to the fabric strands separating the proximate openings. The free ends of each pair of knotted yarn tufts extend in opposite directions from opposite sides of the foundation fabric. Such knotted yarn tufts cover both sides of the foundation fabric and form piles on both sides thereof. Different colored yarn tufts may be used and may be arranged to form predetermined decorative patterns on both sides of the article. The patterns on opposite sides of the article can be the same or they can be entirely different.
