These are the feed dog and needleplate i'm currently using:





Underneath the feed dog and needleplate i've ordered:





As you can see they are quite different. The opening behind the feed dog looks smaller and is divided into 2 smaller openings. Hope this wil prevent the material getting stuck. I'll let know as soon as the new parts are installed.

Although it often happens with thick material, it will olso occasionally happen when just sewing a french seam for instance.
I'll let know if it wil makes a difference.
