I've removed the waistband from a pair of jeggings and an reattaching it lower down. I played eeney meeney miney mo with the stitch selection (though I dare say straight stitch would have been fine) and thought I'd try stretch overlock. It seemed fine, apart from the fact that the edge of the fabric had to go right through the centre of the foot so the fabric wasn't held in position that well. And when I stopped, lifted the foot, realigned the fabric very slightly, and continued, the stitching jumped to the side.... like this:
This isn't from me moving the fabric, as I was just shifting the top layer to stop it curling up. It's as if the needle 'forgot' its position so jumped in the wrong direction.
Is this to be expected? Surely it's normal to need to raise the foot to realign things occasionally and it shouldn't disrupt the stitch?
