I tried to do a zigzag on my sewing machine and it started to stitch all weird like. almost like the top was on the bottom and bottom was on top. I played around with other stitches and they all were the same.
I then went back to straight stitch and now the machine is doing the above and the top thread is really loose.
I have tried to adjust the tension and it just seems to make it worse.
Ive tried to change the needle and thread but it doesnt make a difference.
Does the machine need to be looked at or is there something else i can try?
machine servicing here is really expensive. Often cheaper to buy a new sewing machine.
Thanks in advance
