How to Sew a Curved Seam

In some sewing projects, you may be asked to produce a curved seam. It's a simple thing to sew, once you know how.

Steps

1
Face the material with the wrong side out. This is presumed, unless your pattern states otherwise.
2
Measure the required space between the edge and where your sewing line will go. This makes the seam allowance.
3
Clip a "V" shape from the raw edge of the fabric to the line of your seam allowance.
4
Clip out more "V" shapes at evenly spaced intervals all the way along the curved seam edge.
5
Sew the curved seam at the seam allowance line. The little clipped "V"s will ensure that the seam allowance lies flat on the inside.
6
Trim if needed. Then turn the sewing the right side out. Continue sewing other parts of the fabric item as instructed by the pattern.
