before starting to sew
1.make sure the top thread & bobbin thread have a thread tail of 3 to 6 inches
2.make sure the thread tails are pulled behind the needle toward the back of the machine

then put the fabric under the presser foot to sew

when your finished with the seam, after the thread is cut from the fabric,, leave the thread tail the same as above before starting to sew again

What is blocking the hook and shuttle? I am not too sure what you are asking, where are you trying to put the thread? Please, be more clear.

is the thred bunching up on the fabric, or in the case?

Put 4 colours of thred on the machine , set all tention knobs to 0 stitch and see what colour is not tight, adjust the colour that is not tight. Also use jersey ball point no 80/12 needles it work on all material E-Mail me [email protected] From Willem SA

Thred breaking is one of the following: tention to tight, wrong thred, wrong needles - use jersey baal point 80/12 needles for all material and thred, bobbin tention too tight. [email protected]

It would help to know the brand and model of the sewing machine you are referring to.

the problem of your machine is your bobbin. put it in her right position. adjust your tension.

Use left twist thread

after i looked over the machines thred routing i found a pice of thred jamed in under the top clear plastic panel i took thihs panel off and removed the thred ,cleaned in there put it back togather and it now works fine just what i found hope it works for others
