I drew the lines just like that on the fabric. Had to cut four, two for each poi. I calculated that it would take no more than one hour.
I inserted a green lace to the seams and decorated it a bit with machine stitches. I must admit a little miscalculation. In the end it took about three hours :-) Maybe more.. End are folded and sewn to make a hole for the loops and the planned filling is sand.
