Abstract: An exemplary method for fabricating duvets, shams, or pillowcases comprises: providing first squared fabric leftover pieces of a first color; providing second squared fabric leftover pieces of a second contrasting color equal to the first pieces; stitching together the leftover pieces arranged in a checker pattern, wherein each first square is adjacent to second squares and vice-versa, forming a top and a bottom joint sheets substantially equal and rectangular, both having two longitudinal sides and transversal sides; superimposing the top sheet on the bottom sheet, stitching them together along the longitudinal sides and one transversal side by a sewing machine, thereby coupling them. A comforter can be made of one top joint sheet (produced by the above method), one heat insulation layer, and one regular bottom sheet. A method modification includes arranging a joint sheet from strips; wherein each strip differs from its adjacent strip or strips by contrasting colors.
