I recently placed my sewing machine on a 42" table so I could try sewing while standing up.
Problem.....foot pedal wouldn't reach the floor.
The attractive yellow thing is 2" wide tubular polypro Webbing. Webbing is screwed to shelf behind the foot pedal. A flat stick is inserted into Webbing on the floor and elevated for use as a pedal. A binder clip on the floor end of the Webbing allows me to adjust the inserted flat stick.
Device is easier to use than the actual foot pedal.
