Thank you for all your advice.
I must agree with jimr on the video you posted Suicide. I tried it and there is no way I can press two needles through the hole at once. But the way to control the thread seems to be right
Although I haven't sewn that much I already feel uncomfortable sewing without having the two needles and the awl in my hands. It feels that i'm not able to stab a hole with the awl without having the needles in my hands :D
Jim> Nice to hear how you start and end the sewing. I haven't seen this advice anywhere else. I will give it a try.
Just a quick totally unrelated question. Is there a machine that is able to sew with saddle stitches or do they all use lock stitches, loop stitches or some other inferior stitch?
