If you don’t know how to tape the bias binding in curves, take note!
To learn how to bevel the tape in curves, it is necessary to open the short edge of the bevelled tape, align the edge of the canvas and install all the pins. To help better design the compensation tape, it is necessary to cut the seams and glue them to the centre of the curve. Then take it out.
You can sew a stitch along the edge of the gutter and press and spray it for best results.
