Janome Automatic Buttonhole Sewing Foot Guide

This buttonhole sewing foot attachment lets you use Janome's 1-step buttonhole sewing function easily. It engages the sensor of the machine, and is adjustable using a M2 screw. You are advised to try the size on a spare piece of fabric first, as the size of the gap doesn't exactly correspond with the size of the button hole.

Just place the jig over the place of the buttonhole oriented so that the arm without the M2 screw is touching the buttonhole sensor lever. Then put your machine on the correct mode and let it work.

Have fun!

Here's a youtube video on how to use it: 

Resized the model to fit Janome sewing foot and added two arms, one taking an M2 screw, that engagages the buttonhole sensor foot of Janome machines.
