where to find bobbin winding tire for Singer 15-91
I need to replace the bobbin winding tire on my Singer 15-91. I know I can find this part online. I had someone tell me that I can find this part easily at fabric stores such as Joann's. Can this part be found easily locally (in general - I know it depends on where someone lives, I am in the DFW metroplex)? Or have you found that these parts generally need to be ordered online?
