Hello
@julelin I'm still trying to get used to this machine. Work has pretty much dried up for me so I haven't used it as much as I might have done in normal times.
I recently replaced a zip in some denim trousers. Not really jeans as we think of them. These were trousers made out of a fairly soft denim, and it stitched about 7 layers on the waistband at the top of the zip.
I went slowly but it managed.
Then I came to stitch the little bar-tack at the bottom of the fly...hmmm....about 4 or 5 layers, and it WOULD NOT stitch.
Tried about four times and it just spat up a birds nest underneath. I gave up and used another machine in the end.
Now, I don't know if this was user error,
but today I replaced a zip in some regular trousers, and the same thing happened again at the bottom of the zip. Got it to work at my second attempt by approaching the stitching from the opposite direction.
Five layers of cotton sheeting?....hang on a tick....
Right, I've just found out a scrap piece of Egyptian cotton sheeting and folded it up into 6 layers. It stitched absolutely fine. It's nice quality cotton, fine and soft. I don't know if you intend to use a thicker or stiffer fabric than this.
I added a folded over piece of lightweight denim and it stitched that too. So eight layers here and no funny thumping noise.
Sandra.
