The seam used in mitring corners is formed by joining two pieces of materials together, each cut at an angle of 45 degrees, and sewing them so as to form a right angle.

Materials. - These materials are required for this lesson : Two strips of material four inches wide; needles, "be-tweens" or "ground downs"; cotton; scissors; tape measures.

1.   Fold the corners of the strips to be mitred on a true bias, and crease.

2.   Cut with the inside of the crease up.

ILL. 37. - Material Cut and Sewed.

ILL. 38.- A Mitred Corner.

3. Place the bias ends together with the wrong side of each piece out. See Illustration No. 37.

4.  Baste together with even basting one-fonrth of an inch from the edge.

5.   Open the seam and see if it has been correctly placed.

6.   Sew with a backstitch directly below the basting.

7.   Press the seam open and trim the corners neatly. See Illustration No. 38.

To Mitre the Corners of a Hem.*

Materials. - These materials are required: A handkerchief or some similar article requiring a mitred corner; needles; cotton; scissors; tape measure.

1.   Cut off the corner one-fourth of an inch deep.

2.   Fold the two sides down one-fourth of an inch and crease carefully.

3.   Crease each side down one inch from the edge of the first turn.

4.   Mark where the crease meets by a dot or pinhole.

ILL. 39. - Mitred Corner Cut and Ready for First turn of Hem.

ILL. 40. - Mitred Hem Basted.

*Advanced work.

See Illustration No. 39, letter A representing dot or pinhole.

5.   Open all the folds and make a diagonal crease across the corner one-fourth of an inch outside the spot marked by the dot A.

6.   Cut on the crease just made. See (B and C) on Illustration No. 39

7.   Turn down the bias edge one-fourth of an inch. (Be careful not to stretch it.)

8.   Fold and baste the sides of the hem, making the two edges meet at a right angle. See Illustration No. 40.

9.  Hem carefully, taking the stitches at the mitred corner so that they will not show through on the right side.

10.   Test your skill in this lesson by repeating the lesson on similar corners.
