Very smoothly, precisely on equity and transverse threads, cut a piece of fabric of suitable size.
Wrap once the edge on the underside of about 3 mm and pave the seam “forward needle” white thread to sew a stitch of about 2-3 mm. At the corners to make an additional track to further tissue on crumbled (I apologize for the not very high quality, some photos, there has been no camera had to take pictures on the phone).
Tie edge retreated by about 3 mm, stitch width of about 2 mm. Then knit a number of conventional columns, without sc.
Next row Knit: three columns with sc; 2 air loop and again with three column, departing from the previous column 1 loop.
Next number 6 stitches, column 1 without over 2 air loops of the previous row.
And closes the series: from the middle of the arc of each loop of the previous row – 2 column with sc, 1 air loop, 2 column with sc, 1 air loop, 2 column with sc.
