Want to get crisp points when stitching-in-the-Ditch around points?
Stitch beyond the point by one or two stitches. That will give you enough of an angle to stitch down the adjacent side and get a crisp point without rounding or squaring off your corner turn.
When should you Stitch-in-the-Ditch?
Of course SID (Stitch-in-the-Ditch) is a lost art, but if the piecing is spectacular you may want to SID the brilliant piecing instead of just stitching over it.
Use a straight-edge ruler to guide your hopping foot or a Stitch-in-the-Ditch foot for straight thread paths.
Your customers will love you for it and so will the judges!
Hope that helps!
