I have lots and lots of bobbins for my old singer..everytime I made clothes for the kids or costumes or curtains, or....I needed differnt color thread, so I've got bobbind wound with every coler i have!!! but I'm just starting to aquire extra bobbins for the new pfaff, but i did finally find a store on ebay that sell genuine pfaff bobbins(or so they say) and I emailed and asked if what they were selling me would fit my machine. I have them now and they look exactly like what came with the machine. I buy them 20 at a time!! You can never have too many :lol: :lol:
