Chapter  26  Basic  Sewing  Skills  453  •  Pinked  fi  nish.  If  the  fabric  does  not  ravel  easily,  a  pinked  edge  will  offer  an  attractive  fi  nish.  Machine  stitch  the  facing  edge  ¼  inch  from  the  unnotched  edge.  Trim  the  edge  with  pinking  shears.  •  Overcast  fi  nish.  On  heavy  fabrics  that  ravel  easily,  overcast  the  raw  edge  either  by  hand  or  by  machine.  Attaching  the  Facing  To  attach  the  facing  to  the  garment,  fol-  low  these  steps:  1.  Pin  the  right  sides  together  matching  notches  and  seams.  2.  Stitch  the  facing  to  the  garment.  Backstitch  at  the  beginning  and  ending  of  the  seam  to  secure  the  stitches.  3.  Trim,  grade,  and  clip  the  seam  as  needed.  4.  Press  the  seam  toward  the  facing.  5.  Understitching  the  seam  gives  the  edge  a  crisp  fi  nish  and  prevents  the  facing  from  rolling  to  the  outside.  Understitching  is  a  row  of  stitching  you  sew  close  to  the  seam  line  through  the  facing  and  the  seam  allowances.  When  understitching,  sew  on  the  right  side  of  the  facing,  keeping  the  seam  allowances  toward  the  facing.  Pull  the  fabric  slightly  on  either  side  of  the  seam  line  as  you  sew,  26-18.  6.  Turn  the  facing  to  the  inside  and  press.  7.  Fasten  or  tack  the  free  edge  of  the  facing  to  the  seam  allowances  with  hand  stitches.  A  quicker  option  is  to  stitch-in-the-ditch  on  the  outside  of  the  garment.  Using  short  machine  stitches,  stitch  directly  into  the  well  of  the  seam  through  all  layers  of  fabric.  Interfacing  Interfacing  is  a  layer  of  fabric  between  the  garment  and  the  facing.  It  adds  body  and  fi  rmness  to  the  outer  fabric.  It  also  prevents  stretching  and  provides  extra  reinforcement.  You  will  use  interfacing  in  collars,  cuffs,  lapels,  facings,  and  waistbands,  and  in  areas  of  such  stress  as  under  buttons  and  around  but-  tonholes.  See  26-19.  Interfacing  gives  garments  a  better  appearance  and  makes  them  more  durable.  A  wide  variety  of  interfacing  fabrics  are  available.  Consider  the  look  you  want  to  achieve.  A  heavier-weight  interfacing  gives  a  crisp  look  whereas  a  lighter  weight  gives  a  softer  look.  As  a  general  rule,  choose  an  interfacing  that  is  a  little  lighter  in  weight  than  your  garment  fabric.
