Messed up my machine please help! Singer 401a
I cleaned the old grease off the cylindrical part and applied new grease and added grease to the grease points and I added oil to the oil points (white lily) grease - (superlube) and now it’s seizing up on me and barely wants to see through anything. Really freaking worried!! It sewed amazing before this and sewed through like 7 layers of denim perfectly. What have I done 😭 please help.
