A method for constructing a double fleece knit fabric using a circular knitting machine is disclosed. Lay-in, tie-in and knit-in yarns (57, 58 and 59) are fed at respective first, second and third yarn feeders (60, 61 and 62) to the needle. The lay-in and tie-in yarns (57, 58) are caught by the outward, oblique and upward recession of the sinker. The knit-in yarn (59) is fed to the needle (2) and when received onto the upper edge (8g) of the second nose (8e) is drawn down onto the upper edge (8f) of the first nose (8d) of the sinker (8) when the needle (2) is lowered. The needle (2) is lowered to a stitch loop forming position while the sinker (8) is receded from the innermost lower position to the outermost upward position so that the knit-in yarn (59) falls onto the stitch forming ledge (8a) and the respective lengths of the tie-in yarn (58) and knit-in yarn (59) in the needle hook are drawn downward with the older tie-in and knit-in loops being cleared from the needle (2) so as to form a new tie-in loop and knit-in loop over the stitch forming ledge (8a).
