i have searched the internet for answers but have come up empty handed. i hate to bother anyone for what is probably so simple for the expert. it boggles my brain.. i have a singer 111w155 and for some unknown reason it wont feed any kind of fabric or leather. i di have the feed dogs off to use a binder that had a custom made feed dogs and needle plate to be able to use the binder. i didn't actually use the binder as the binding tape was way to narrow ss i removed everything and replaced the originals. i have not adjusted or tampered with anything else I've looked and looked at every visible part but not actually turned a screw. i am at my wits end as i have a couple jobs coming in this week and this is my only machine.. please help I'm on the verge of bawling
