Bound Buttonhole Triangular Shape

 

I learned about this triangular shaped bound buttonhole in 1993 when I bought the book

  Couture the art of fine sewing  by Roberta Carr. I have made these kind of triangular buttonholes several times , the one above was done in a raincoat .

 I made an example to show you the steps  how to make such a triangular buttonhole and kept my text to a minimum because of copyright issue. 

   Step 1, measure the button length and space between the edge and the buttonhole.

 Step 2, mark and transfer the lines ( horizontal and wide) on the interfaced fabric .

Step 3, thread trace the buttonhole length and wide on the patch.

 

Step 4, draw the triangular button lines.

Step 5, stitch using a tiny stitch length start anywhere on one of the long lines  and stitch 2 diagonal stitches at the corners and at the point, overlap the beginning of the stitches with a few more stitches. I used a red thread for easy viewing.

.

 Step 6, draw lines so you can slash the patch in 3 sections . The lines of the patch marked in red, cutting lines inside the buttonhole in black. 

                 

  Step 7, turn patch section 1 to the inside and press .

Step 8, press patch section 2  along the stitching line.

   Step 9, do the same with patch section 3 as above.

Step 10, wrap patch section 2 and 3 around the horizontal slit edges on the inside and press from the inside .

 Step 11, stitch the triangular tab to the patch through all the layers so it will be permanently attached.

Step 12, cut away excess fabric of the patch.

Done.
