Using a Sewing Machne Foot Pedal The Easy Way
The tendency is to use it in the orientation below. Notice how the heel is suspended in air? You have to hold up you foot and push down with your toe. This is usually not the easiest way.
Instead, flip the controller around the other way. You will be able to rest your heal and foot on the floor rather than devoting muscles to suspending it in the air. To control the speed of the machine, just push down or release using the ball of your foot on the edge of the controller. Give it a try. You will be surprised at how much easier it will be to get more precise control over the speed and how much more comfortable it feels for most people.
