Carrickmacross lace is a form of lace that may be described as decorated net. A three-layer 'sandwich' is made consisting of the pattern (at the bottom), covered with, first, machine-made net and then fine muslin, through which the pattern can be seen. A thick outlining thread is stitched down along the lines of the pattern, sewing net and fabric together. Loops of thread known as 'twirls' are also couched along the outer edge. The excess fabric is then cut away. Some of the net is then usually decorated further with needle-run stitches or small button-holed rings known as 'pops'. Occasionally bars of buttonhole stitches are worked over fabric and net before both are cut away.[1]
