LvxLeather Report post Posted January 22 I am new to using sewing machines and have an issue with corners not being held tight. I'm assuming it's a tension issue possibly but I'm not sure. I figured someone here will know exactly what the problem is. I'm using a Cobra Class 26 cylinder arm machine, 138 thread, 24 needle. Quote Share this post Link to post Share on other sites
Dwight Report post Posted January 22 (edited) I may be wrong . . . but from what I'm seeing . . . your needle is way too large . . . and if this is the top . . . your bobbin thread needs tightened . . . if this is the underside . . . your top thread is loose.

Northmount Report post Posted January 22 Make your turns after the needle has risen about a 1/4". Don't lift the presser foot so far that it releases the thread tension. And of course look at the above post. Quote Share this post Link to post Share on other sites
