Sewing machine will not sew, please help
My friend recieved a second hand singer 301 brown sewing machine. The machine first would sew like a dream, but then after about 4 inches the problems started. The top thread knotted underneath the feed dog (around the bobbin), the thread Ripped and tared with tangles under the feed dog; the thread constantly rips from the needle; it punches holes instead of sewing (skips ALL stitches).
That last problem has also been affecting MY babylock/denim proII (b15) for atleast 5-6 years!
Can anyone help? We have tried what seems to be everything to make her machine go for hours on end, but to no avail. Please, can someone help?
