Leather buttonholes are some of the easiest buttonholes you will ever make! One of the advantages of leather is that it does not ravel. Always stitch a test sample to check the length of the buttonhole before making leather buttonholes on your project.

Pink the edges of the interfacing that will sit to the inside of the garment or project. Interface the area of the buttonhole using the technique described here.

Chalk the length of the buttonhole. The width of the buttonhole should be 3/8".

Carefully cut down the center of the buttonhole and V into each end.

Apply rubber cement to the wrong side of the buttonhole. Let it dry slightly to become tacky.

Fold back the edges of the buttonhole. Pound lightly on a wooden board to hold the edges down.

Use some scraps of leather to make welts for the buttonholes. Scraps should be about 1 1/2" wide by the length of the buttonhole plus 1". One long strip can be used to make several welts. Apply rubber cement to the wrong side of the leather. Fold strip in half wrong sides together and press to flatten. Cut into lengths that equal the length of the buttonhole plus 1".

Now apply rubber cement to the turned back edges of the buttonhole.

Center the welts over the glued area. Check the right side to make certain that the welts are perfectly aligned in the center of the buttonhole.

Trim the outer edges of the welts into an oval shape.

Turn back the facing. Edge stitch around the buttonhole leaving long thread tails at the beginning and the end. Knot off the thread tails and bury the ends in between the layers.

Carefully cut away a rectangular opening from the back of the buttonhole.
