Question on the Featherweight upper tention.
When I am sewing the upper thread take up leaver when at the highest position, all the tread it tight. But as the take up leaver comes down there is slack in the thread.
Is the thread supposed to be tight? I am wondering if this is the problem I am having. When the thread has slack then it bunches underneath the fabric.
I can get a picture if I didn't make myself clear.
Thanks
