I am just getting needle holes and no stitches

Is the thread slipping out of the needle as you start to sew? (that's happened to me before)

[sparrowlegs]

yes started to do that last night, after I rethreaded with new cotton and bobbin with the same cotton 
so frustrating!

If that's what it's doing, it helps to hang on to the thread until you've sewn a couple stitches -- that way it can't slip out of the needle.

thank you I will try that today,
I have been intouch with my local sewing machine shop, and a service is £25 plus parts....so I will try your advice today, plus have it serviced as the tension spring may have 'gone' said the lady at the shop.
