3. Click the point that you want to move.
   The selected point appears as a small black square.

   Although a region may seem closed, if the sewing attributes cannot be specified for the region, the region may not actually be closed.
   Please make sure again that the region is fully enclosed.
   In the Figure Handle Stage, you can enclose the region and divide the region into smaller regions with the line drawing mode . ( This is useful to find out the regions that are not fully enclosed. )
   In the Sew Setting Stage, please apply the sewing attributes to the region again.
